Wang, Linqing published the artcileA tandem asymmetric oxidation-oxa-Michael sequence for dearomatization of β-naphthols, Formula: C4H7NO2, the main research area is spiro furan naphthalene preparation enantioselective; naphthol phenyl benzooxazirenoisothiazole dioxide hydroxylative dearomatization tandem.

A catalytic asym. hydroxylative dearomatization reaction was disclosed, and the products could smoothly transform into spiroannulation adducts I [R = H, Me, Et, etc.; R1 = Me, Et, Bn] by simply treating with a base under mild conditions. Novel in-situ generated magnesium catalytic methods were developed by application of combinational ligands. Related concise transformations of the spiroannulation adducts were carried out.

Koivusalo, M. published the artcileOn the yield of respiratory-chain phosphorylation, Related Products of oxazolidine, the main research area is .

The P/O ratio of guinea-pig heart sarcosomes oxidizing glutamate was 2.42-2.87 (mean 2.63) when the incubation procedure of Smith and Hansen (CA 61, 2077h) was followed. The steady-state P/O ratio of rat-liver mitochondria oxidizing glutamate, under the conditions used by Gurban and Cristea (Rev. Roumaine Biochem. 1(1), 51-7(1964)), was 2.5. Preceding this steady-state value there was a burst of phosphorylation in the 1st few minutes, which was not accompanied by a corresponding increase in O uptake. The true yield of oxidative phosphorylation was given by the ratios of the rates of phosphorylation and oxidation when the steady state was achieved, and that the burst of phosphorylation was related to the previous history of the mitochondria. The cause of the burst was not known.

Ferreira, Jasmin published the artcileChemoselective room temperature E1cB N-N cleavage of oxazolidinone hydrazides from enantioselective aldehyde α-hydrazination: synthesis of (+)-1,4-dideoxyallonojirimycin, Recommanded Product: (R)-4-Methyloxazolidin-2-one, the main research area is enantioselective aldehyde hydrazination oxazolidinone hydrazide cleavage deoxyallonojirimycin synthesis; E1cB elimination alkylation enantioselective synthesis deoxyallonojirimycin oxazolidinone hydrazide bromomalonate.

Room temperature E1cB N-N cleavage of oxazolidinone hydrazides via N-alkylation with di-Et bromomalonate and potassium or cesium carbonate as base in acetonitrile is presented. The new method has a much improved chemoselectivity, which is illustrated by a concise total synthesis of the piperidine iminosugar (+)-1,4-dideoxyallonojirimycin.
