Highly Efficient Kinetic Resolution of Aryl-Alkenyl Alcohols by Ru-Catalyzed Hydrogen Transfer

open access: yesMolecules, 2021
No matter through asymmetric reduction of ketones or kinetic resolution of secondary alcohols, enantioselective synthesis of the corresponding secondary alcohols is challenging when the two groups attached to the prochiral or chiral centers are spatially

Takotsubo cardiomyopathy secondary to alcohol withdrawal

open access: yesGlobal Cardiology Science and Practice, 2022
Physical, mental, and emotional stressors have been well known to adversely affect cardiac function. A rare complication of such stressors is stress cardiomyopathy, otherwise known as takotsubo cardiomyopathy. First identified in Japan in the 1990s, takotsubo cardiomyopathy classically presents with systolic dysfunction and apical ballooning.

Secondary fatty alcohols of Mycobacterium xenopi [PDF]

open access: yesJournal of General Microbiology, 1992
Secondary alcohols of Mycobacterium xenopi were studied by gas chromatography and gas chromatography-mass spectrometry. Mycobacterial cells were hydrolysed and the liberated alcohols separated by extraction and analysed both underivatized and as trimethylsilyl, methyl ether- and pentafluorobenzoyl derivatives.
