Received: 10 April 2012; in revised form: 25 April 2012 / Accepted: 7 May 2012 / Published: 9 May 2012 Abstract: This review covers the construction of drug-like 2H-benzopyrans and related libraries using solid-phase parallel synthesis. In this context, the preparation of substituted benzopyrans such as mono-, di- and trisubstituted benzopyran derivatives and additional ring-fused benzopyrans such as benzopyranoisoxazoles, benzopyranopyrazoles, six-membered ring-fused benzopyrans, and polycyclic benzopyrans are highlighted. Keywords: combinatorial chemistry; solid-phase synthesis; chemical library; drug-like molecules; 2H-benzopyran 1. Introduction Combinatorial chemistry has become an extremely powerful technique for the generation of drug- like and biologically active small organic molecule libraries
