Boron-Zinc Exchange in The Diastereoselective Arylation of Sugar-Based Aldehydes: Stereoselective Synthesis of (+)-7-epi-Goniofufurone and Analogues

Abstract

The substrate-controlled diastereoselective arylation of chiral aldehydes readily available from carbohydrates is described, using the boron–zinc exchange reaction to generate the transferable aryl groups. The methodology developed was applied to the total synthesis of the styryllactone (+)-7-<i>epi</i>-goniofufurone and analogues thereof.
