Abstract

The reactions of 4-nitroaldehydes 9 and 10 with dihydroxyacetonephosphate (DHAP) catalyzed by fructose-1, 6-diphosphate aldolase from rabbit muscle were studied. Starting from 9 or 10, only one main stereomer of nitrocyclitol 8 was isolated. A highly stereoselective intramolecular cyclization (Henry reaction or nitroaldol reaction) took place under acidic conditions during the aldolase catalyzed condensation and phytase catalyzed phosphate ...
