Stereospecific Synthesis of cis/trans-dicarbamates

Abstract

The efficient synthesis of a new class of allylic cis/trans-dicarbamates are described. Allylic diols as key intermediates of the targeted compounds were prepared in a facile way, starting from p-benzoquinone. Reaction of allylic diol compounds with p-TsNCO resulted in the formation of cis/trans-dicarbamate groups. The structure of cis/trans-dicarbamates were determined by 1H-NMR, 13C-NMR, FT-IR and elemental analysis techniques.
