Direct C-glycosylation of organotrifluoroborates with glycosyl fluorides and its application to the total synthesis of (+)-varitriol

A mild, stereoselective, and quick approach to accessing alkynyl and alkenyl C-glycosides via BF3?Et2O promoted coupling of organotrifluoroborates and glycosyl fluorides is reported. The application of this method was further demonstrated by the concise and efficient total synthesis of (+)-varitriol in only seven steps.

Synthesis of polyhydroxylated pyrano-pyrrole derivatives from carbohydrate precursors

The efficient synthesis of novel polyhydroxy-tetrahydropyrano-pyrroles from acetylenic carbohydrate precursors in three to four steps is described. The methodology involves, as key steps, the ring contraction of pyridazine intermediates obtained by an inv
