Popis:	Three hexopyranosides having gem-di-C-methyl group at 2- or 4-positions were synthesized by Michael addition to 2-enopyranosid-4-ulose and 3-enopyranosid-2-ulose derivatives, respectively, followed by hydroboration. A heptopyranosid-6-ulose having gem-di-C-methyl group at C–4 was also synthesized from 4-enopyranosid-6-ulose derivative in a similar way. Article
