Fig. 3From: Gypsum-DL: an open-source program for preparing small-molecule libraries for structure-based virtual screeningSimplified representations of the reaction schemes used to enumerate the D3 library. The spheres represent the bound polymer. a Alkylation of the polymer-bound benzophenone-imine glycine using the alkyl-halide building blocks. b Alkylation using the Michael-acceptor building blocks. c Deprotecting the benzophenone protecting group. d Acylation using the carboxylic-acid building blocks. e Cleaving the polymerBack to article page
