09/29/21 News The Shocking Revelation of 4923-87-9

This is the end of this tutorial post, and I hope it has helped your research about 4923-87-9 .Reference of 4923-87-9

Reference of 4923-87-9, Chemical Research Letters, May 2021. This type of reactivity has quickly become one of the cornerstones of modern catalysis . In a article, 4923-87-9, molcular formula is C8H5BrS, introducing its new discovery.

The enzyme aryl/alkenyl malonate decarboxylase (AMDase) catalyses the enantioselective decarboxylative protonation (EDP) of a range of disubstituted malonic acids to give homochiral carboxylic acids that are valuable synthetic intermediates. AMDase exhibits a number of advantages over the non-enzymatic EDP methods developed to date including higher enantioselectivity and more environmentally benign reaction conditions. In this report, AMDase and engineered variants have been used to produce a range of enantioenriched heteroaromatic alpha-hydroxycarboxylic acids, including pharmaceutical precursors, from readily accessible alpha-hydroxymalonates. The enzymatic method described here represents an improvement upon existing synthetic chemistry methods that have been used to produce similar compounds. The relationship between the structural features of these new substrates and the kinetics associated with their enzymatic decarboxylation is explored, which offers further insight into the mechanism of AMDase. Versatile decarboxylase: Aryl malonate decarboxylase (AMDase) and engineered variants have been shown to catalyse the enatioselective decarboxylative protonation of a range of alpha-heteroaryl alpha-hydroxy malonates with excellent yields and enantioselectivity (see scheme).
