Reduction of 3-(carboxyaryl)isocoumarins with sodium borohydride
摘要:
Reduction of 3-(carboxyaryl)isocoumarins with sodium borohydride proceeds with formation of corresponding 3-carboxyaryl-3,4-dihydroisocoumarins or isomeric dihydrophthalides, 3-(2-carboxybenzyl)-2-benzofuran-1(3H)-ones. Derivatives at the carboxyl group of 3-carboxyaryl-3,4-dihydroisocoumarins and 3-(2-carboxybenzyl)-2-benzofuran-1(3H)-ones have been obtained.

New amino-acid derivatives of 3-arylisocoumarins were prepared via acylation of the amine groups of natural amino acids by phenoxyacetic acids containing an isocoumarin substituent on the benzene ring.
