Synthesis, structure revision, and absolute configuration of (+)-didemniserinolipid B, a serinol marine natural product from a tunicate Didemnum sp.

[structure: see text] En route to proving the absolute and relative stereochemistry, through synthesis, of (+)-didemniserinolipid B (1), the first natural serinolipid isolated from a tunicate Didemnum sp., it was discovered that the isolated natural product was in fact the 31-sulfate configured 8R,9R,10R,13S,30S. This structural reassignment was only possible after the development of a microwave-assisted method for the sulfation of unreactive hydroxyl groups.

Ring Contraction of 1,2,4-Benzoxadiazines to Benzoxazoles

1,2,4-Benzoxadiazines (1) undergo a ring contraction to benzoxazoles (2) on heating.Other products of the reaction have been identified as nitrogen and ammonia.A mechanism is suggested for this reaction which involves (i) electrocyclic ring opening to an o-benzoquinone imine, (ii) recyclisation to a diaziridine, and (iii) extrusion of a nitrene fragment.Evidence is presented which is consistent with this proposal: thus, the benzoxazole (7) is produced on heating 3,5-di-t-butyl-o-benzoquinone with benzamidine and 4-nitrobenzoylnitrene is intercepted as the ylide (11) from the thermolysis of the substituted benzoxadiazine (10).

Palladium-catalyzed cross-coupling reaction of azides with isocyanides

An efficient palladium-catalyzed cross-coupling reaction of azides with isocyanides is developed, providing a general synthetic route to unsymmetric carbodiimides with excellent yields. This method shows a broad substrate scope, including not only aryl azides, but also unactivated benzyl and alkyl azides. Furthermore, from readily available substrates, Pd-catalyzed coupling with a tandem amine insertion cascade to obtain unsymmetric trisubstituted guanidines has been achieved in a one-pot fashion.

Grignard reactions to chiral oxazolidine aldehydes

Modest to high levels of asymmetric induction are observed with Grignard additions to Garner type aldehydes. The resultant secondary alcohols are important precursors of chiral building blocks for asymmetric synthesis and we have demonstrated that they can be readily converted into their respective gamma-hydroxy-beta-amino alcohols and beta-hydroxyamino acids. Additionally, aryloxy ethers, important components of many natural products, can be obtained from these precursors.

Synthesis of 4-methoxy-2,3,5-trimethylpyridine: a specific building block for compounds with gastric-acid inhibiting activity.

A new synthesis of 4-methoxy-2,3,5-trimethylpyridine (2), an important building block for the preparation of gastric-acid inhibiting compounds, is described. Condensation of ethyl 3-amino-2-methyl-2-butenoate (3) and diethyl 2-methylmalonate (4) gives 4-hydroxy-3,5,6-trimethyl-2(1H)-pyridone 5. Reaction of 5 with phosphoryl chloride affords 2,4-dichloro-3,5,6-trimethylpyridine (9a), which, upon hydrogenolysis with palladium on charcoal, gives 2,3,5-trimethylpyridine (10). However, selective hydrogenolysis in acidic solution yields 4-chloro-2-3-5-trimethylpyridine (11). Substitution of the chlorine in 11 with methoxide ion gives 4-methoxy-2,3,5-trimethylpyridine (2), which can be oxidized to the corresponding N-oxide (13). This constitutes a new and efficient route to compound 2 in an overall yield of 43%.

Study of the fragmentation mechanism of protonated 6-hydroxychlorzoxazone: Application in simultaneous analysis of CYP2E1 activity with major human cytochrome P450s

The application of liquid chromatography tandem mass spectrometry for simultaneous analysis of major human cytochrome P450 activities via a single atmospheric pressure ionization (API) LC/MS/MS method has been hampered by the preferred detection of 6-hydroxychlorzoxazone (HCZ), the metabolite of the CYP2E1 probe, chlorzoxazone, under negative API. An initial simulation of the dissociation constants suggested the potential ionization of the enol form of HCZ at low pH, and the accurate mass measurements confirmed the presence of the protonated HCZ signal under (+) ESI at pH 3. However, the CID spectrum of the protonated HCZ resulted in a few intense, but uncommon, fragment ions that could be utilized for specific selected reaction monitoring (SRM) transitions. The deduced elemental compositions of these fragment ions indicated possible aromatic ring opening for the first two intense product ions at m/z 130 and 115, as well as chlorine radical loss for the third ion at m/z 151. Further precursor and product ion scan studies, along with the deuterium ion exchange in solution, revealed the involvement of three distinct pathways of fragmentation. The m/z 186 ? 130 transition, which was shown to be specific in human plasma and rat hepatic microsomes, was further combined with the SRM transition of reserpine (internal standard) and eight probe substrates for human cytochrome P450 isoforms. This led to the development of a full LC/MS/MS method capable of analyzing a total of nine human P450 activities within 3 min, including CYP2E1, using a single assay in the (+) ESI mode. The HCZ assay showed excellent linearity with a coefficient of determination (R2) greater than 0.98 at dynamic range of 0.05 (LOQ) to 40 muM. Preliminary data from the three-day validation of the HCZ assay indicated that the accuracy and precision for quality control samples was within ¡À15% of the spiked concentration at all levels.

Synthesis and characterization of oxazolopyridine and benzoxazole derivatives

Synthesis of piperazinyl-substituted oxazolopyridine and benzoxazole was achieved in three steps starting from aminophenol and carbon disulfide. Condensation of aminophenols with carbon disulfide in ethanol using potassium hydroxide as catalyst gave the required benzoxazole thiol in one step. Treatment of the thiol with piperazine and substituted piperazine derivatives in toluene furnished the titled compounds in good yield. We introduced halogen substitution in the pendant arm of the piperazine derivatives for versatile functionalization. We report the synthesis and characterization of these compounds using high resolution NMR techniques.
