Progress in the synthesis of 2-aminobenzoxazole derivatives

2-Aminobenzoxazole derivatives are a kind of heterocyclic compounds, which play important roles in medicine, biology and material science, and their synthetic methods have attracted much attention. In recent years, many efficient, green synthetic approaches of 2-aminobenzoxazole derivatives using transition-metal or metal-free catalytic systems have been reported. Based on differences of reaction substrates and synthetic methods, the recent advances in the synthesis of 2-aminobenzoxazole derivatives are reviewed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 4570-41-6, you can also check out more blogs about4570-41-6

Efficient transposition of the sandmeyer reaction from batch to continuous process

The transposition of Sandmeyer chlorination from a batch to a safe continuous-flow process was investigated. Our initial approach was to develop a cascade method using flow chemistry which involved the generation of a diazonium salt and its quenching with copper chloride. To achieve this safe continuous process diazotation, a chemometric approach (Simplex method) was used and extrapolated to establish a fully continuous-flow method. The reaction scope was also examined via the synthesis of several (het)aryl chlorides. Validation and scale-up of the process were also performed. A higher productivity was obtained with increased safety.

Benzoxazolamines and Benzothiazolamines: Potent, Enantioselective Inhibitors of Leukotriene Biosynthesis with a Novel Mechanism of Action

A series of benzoxazolamine and benzothiazolamine analogs that inhibit leukotriene (LT) biosynthesis are described.The initial lead, (S)-N-(benzothiazol-2-yl)phenylalanine ethyl ester (5a), was discovered in a screening program for inhibition of Ca-ionophore-A23187-induced LTB4 release in human polymorphonuclear leukocytes (IC50 0.23 muM).Through structural modification, it was determined that hydrophobic substituents in the 5-position and replacement of the phenyl ring of phenylalanine with a cyclohexyl group greatly enhance potency.Several ester bioisosteres that retain potency and enantiomeric selectivity are described.Lead optimization culminated in (S)-N-<2-cyclohexyl-1-(2-pyridinyl)ethyl>-5-methyl-2-benzoxazolamine (43b), IC50 0.001 muM.The compounds described are not inhibitors of 5-lipoxygenase but, rather, act at the level of arachidonic acid release.

Assembling heterocycle-tethered C-glycosyl and alpha-amino acid residues via 1,3-dipolar cycloaddition reactions

(Equation Presented) The 1,3-dipolar cycloadditions of C-glycosyl nitrile oxides and acetylenes to an alkyne and an azide, respectively, bearing a masked glycinyl moiety furnished disubstituted isoxazoles and triazoles. Unveiling the glycinyl group in these cycloadducts afforded C-glycosyl alpha-amino acids in which the two bioactive entities were tethered through rigid five-membered heterocycles. Optimized entries to the same compounds involved the use of unmasked but protected alkyne- and azide-containing amino acids as the partners of 1,3-dipolar cycloadditions.

The vicarious nucleophilic substitution of hydrogen and related reactions in nitrobenzoxazoles

5- and 6-nitrobenzoxazoles 3 and 4 react with nucleophiles exclusively at C-2, giving ring opening products. If position 2- is blocked with phenyl substituent the reaction takes place in the carbocyclic ring affording the VNS products. 2-Methylthio-5-nitrobenzoxazole 7 and its 6-nitro isomer 8 give products which result from addition of a nucleophile to the carbocyclic ring (VNS) as well as to the heterocyclic ring (S(N)Ar and ring cleavage). 2-Methylthiobenzoxazoles can be readily converted to the corresponding benzoxazolones via oxidative hydrolysis.
