Enantioselective oxidation of secondary alcohols by the flavoprotein alcohol oxidase from Phanerochaete chrysosporium [PDF]

open access: yes, 2021
The enantioselective oxidation of secondary alcohols represents a valuable approach for the synthesis of optically pure compounds. Flavoprotein oxidases can catalyse such selective transformations by merely using oxygen as electron acceptor.

Stereospecific Oxidation of Secondary Alcohols by Human Alcohol Dehydrogenases

open access: yesJournal of Biological Chemistry, 1989
The human liver alpha alpha alcohol dehydrogenase exhibits a different substrate specificity and stereospecificity for secondary alcohols than the human beta 1 beta 1, and gamma 1 gamma 1 or horse liver alcohol dehydrogenases. All of the enzymes efficiently oxidize primary alcohols, but alpha alpha oxidizes secondary alcohols far more efficiently than ...

Catalytic Oxidation of Secondary Alcohols [PDF]

open access: yes, 2020
The dioxygen oxidation of alcohols over platinum catalysts has been known for a long time. While of potential importance in synthetic procedures, this process has never found extensive use except in carbohydrate oxidations. Some reasons for this is the fact that this reaction only appears to work well in an aqueous medium in the presence of rather ...

Primary depressives with secondary alcoholism compared with alcoholics and depressives

open access: yesComprehensive Psychiatry, 1993
While a subset of depressed patients are believed to "self-medicate" their depression with alcohol, there are no studies comparing the phenomenological and diagnostic characteristics of patients with primary depression and secondary alcoholism with those of patients with depression or alcoholism alone.
