A novel and flexible synthesis of pyranose spiroacetal derivatives

A three-step approach to chiral pyranose [5,4], [5,5], [5,6] and [5,7] unsaturated spiroacetal derivatives from perbenzylated glucopyranolactone 1 is presented. The strategy involves Grignard addition of vinyl or allyl magnesium bromide to 1 to give 2 and

SYNTHESIS OF A CHIRAL 1,7-DIOXASPIROUNDECENE. A MODEL FOR THE SPIROACETAL SUBUNIT OF AVERMECTIN B1a

The stereocontrolled synthesis of a chiral, polyhydroxy 1,7-dioxaspiroundecene from D-glucose is described.The bicyclic system with a different pattern of substitution can be found in a number of biologically important natural products such as the avermectins and the milbemycins.
