Synthetic studies on altohyrtins (spongistatins): Synthesis of the C1- C14 (AB) spiroacetal portion

The C1-C14 portion of altohyrtins (spongistatins) was prepared in a convergent manner from 3,4,6-tri-O-acetyl-D-glucal via a chelation-controlled methylation of ketone, dithiane couplings with epoxides, and a thermodynamically-controlled spitoacetalization.
