Enantioselective synthesis of (1R,2S,4S)-7-oxabicyclo[2.2.1]heptan-2-exo-carboxylic acid
摘要:
A scalable enantioselective access to (1R,2S,4S)-7-oxabicyclo[2.2.1]heptan-2-exo-carboxylic acid 7, a key precursor in the synthesis of A2a receptor antagonist 1 by means of an enzymatic resolution of the respective butyl ester with lipase A from Candida antarctica, is described.
