Abstract
A synthesis of the neocarzinostatin chromophore analog 2, in which the 2'-N -methylamino group of the natural product has been replaced by a hydroxyl g roup, is described. Thiol addition experiments in organic solvents and DNA- cleavage studies in aqueous solution are also described, and provide furthe r support for the proposed participation of the carbohydrate methylamino gr oup in neocarzinostatin activation.
