Synthesis of carba-β-d- and l-idopyranosides by rearrangement of unsaturated sugars
摘要:
The triisobutylaluminium- (TIBAL) and titanium(IV)-promoted conversions of 6-deoxyhex-5-enopyranosides into highly functionalised cyclohexane derivatives provide intermediates for the synthesis of enantiomerically pure carba-sugars. The preparation of enantiomerically pure methyl carba-beta-D-idopyranoside 1, methyl carba-beta-L-idopyranoside 2 and 5'a-carbadisaccharide 3 is reported. (C) 2000 Elsevier Science Ltd.
