Synthesis of caryophyllose. Use of n-BuLi/Na-O-t-Bu in the coupling of highly functionalized ketones and dithioacetals

The C-4 branched monosaccharide caryophyllose 2a was synthesized by, convergent approach relying on the coupling of metalated dithioacetal 4b with ketone 3. Combined use of n-BuLi and t-Bu-ONa as deprotonation system for 4b turned out to be decisive for the success of this coupling. (C) 2000 Elsevier Science Ltd.
