Facile Procedure for Generating Side Chain Functionalized Poly(α-hydroxy acid) Copolymers from Aldehydes via a Versatile Passerini-Type Condensation

Organic Letters, 2010
A general method for synthesizing alpha-hydroxy N-acylindoles in one-pot via an acid-catalyzed condensation of a convertible isonitrile with water and various aldehydes is presented. These intermediates were incorporated into poly(alpha-hydroxy acid) copolymers bearing residues with functionalizable side chains, which could be further modified through ...
