Enantioselective total syntheses of slagenins A-C and their antipodes.

Biao Jiang1, Jia-Feng Liu, Sheng-Yin Zhao.   

Abstract

Full details of the total syntheses of slagenins A-C (1a-c) and their antipodes (2a-c), novel bromopyrrole alkaloids with a unique tetrahydrofuro[2,3-d]imidazolidin-2-one moiety, are described in which their absolute stereochemistry was established. The key step in the syntheses involves the efficient condensation of dihydrofuran-3-one or glyoxal with urea to construct the slagenin bicycle core.
