Lipase Ps-C Catalysed Hydrolysis Of Aryl Deesters: A New Route To The Synthesis Of Achiral Half Esters
摘要:
Pseudomonas cepacia lipase supported on ceramic particles (PS-C) offers a simple alternative route for the synthesis of achiral half esters, with very high yields, easy work up and remarkable substrate selectivity, as it cleaves only phenolic esters having a phenyl group (i.e. C6H5-O-CO-C6H5).
The present invention relates to methods of preparing fused ring indeno compounds that involves reacting together a dienophile and a lactone compound, in the presence of a catalyst, and a carboxylic acid anhydride. With some embodiments, the fused ring indeno compound is represented by the following Formula (I-A), the dienophile is represented by the following Formula (II-A), and the lactone compound is represented by the following Formula (III-A):

A variety of aryl acetates are cleaved to the corresponding phenols using sodium perborate in methanol under mild conditions (25 °C). The effectiveness of this protocol is manifested in its tolerance of different functional groups and selectivity of deprotection towards aryl acetates whereas alkyl acetates are found to be unreactive under these reaction conditions.
