The other main products were the corresponding cyclopentylhydroxyketone and oxetane. A reaction mechanism was proposed.Reaction Kinetics, Mechanisms and Catalysis
The N 1s can be divided into the several peaks (Fig. 3c). The peak of 398.53 eV mainly corresponds to N of triazine ring with a carbon binding form. The peak of 399.77 eV can mainly be contributed to relative tertiary N bonded with the C atom; while, the peak of 401.10 eV is deri...

Constructing benignE. colicatalysts for the production of PDO could be beneficial to commercial production becauseE. coliis well studied in metabolic mechanism, low cost and easy to culture. An enantiomerically pure R-1,2-PDO was produced from glucose in an engineeredE. coliand 0.7 g/L 1,2-...
Our current understanding of the catalytic mechanism suggests that the reactive ketone of a steroid molecule must be located near to the nicotinamide ring from which hydride is transferred, and must also form hydrogen bonds with the conserved His117 and Tyr55. Therefore, other HSDs are likely to...

The invention provides a process for the selective oxidation of a primary or secondary alcohol to an aldehyde or ketone and for the oxidation of a 1,2-diol to an α-ketol or α-diketone which comprises contacting the alcohol or 1,2-diol ... F Marco,S Marco,S Simona - EP 被引量: ...
activity against etoposide resistant cells [16,17], while compounds such as (5) which can form water soluble salts have increased antitumour activity and improved drug resistance [18], and compounds such as (6) exhibit improved activity and are reported to have a novel mechanism of action [...
