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.

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.

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).

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.

Development of electroorganic reactions utilizing stabilized reactive species and its application to organic energy storage materials

Reactive species generated by the oxidation and reduction of organic compounds are generally unstable. To utilize the reactive species as intermediates for organic synthesis and functional materials, it is crucial how to treat them. In this headline, electrochemical reactions utilizing stabilized reactive cations, which enabled benzylic C-H/aromatic C-H cross-coupling, aromatic C-H/C-H cross-coupling, and aromatic C-H amination are demonstrated. Furthermore, energy storage materials utilizing stabilized anions, which enabled to develop organic materials for lithium-ion batteries with high voltage of ca. 3V and solvent-free redox flow batteries with high energy density, are demonstrated. These studies show the usefulness of stabilized reactive species.
