Synthesis of D-apio-beta-D-furanosyl maleimide, an analogue of showdomycin with transposed hydroxymethyl group

摘要

Apioshowdomycin (3-(D-apio-beta-D-furanosyl)-1H-pynole-2,5-dione, 2) has been prepared as an analogue of the C-nucleoside showdomycin (1) in eight steps and with 5% overall yield, starting from 2,3-O-isopropylidene-D-apio-beta-D-furanose (3).
