A GENERAL-SYNTHESIS OF BETA-HYDROXY ACYLSILANES, ALPHA,BETA-UNSATURATED ACYLSILANES, AND BETA-OXO ACYLSILANES - APPLICATION TO THE SYNTHESIS OF SUGAR DERIVED ACYLSILANES
We report a convenient method for synthesis of functionnalized acylsilanes (beta-hydroxy, alpha,beta-unsaturated and beta-oxo-acylsilanes) from epoxides and 2-lithio-2-trimethylsilyl-1,3-dithiane. This method was adapted to 5,6-anhydro-D-glucose derivative to prepare various glucose derived acylsilanes.
