2,3-Sigmatropic rearrangement of nucleophilic carbenes. A new approach to stereospecific synthesis of carbon–carbon bonds
Abstract
S-Methyl-S-(3,3-dimethylallyl)carbene, generated by Bamford–Stevens reaction of the corresponding toluene-p-sulphonylhydrazone, undergoes a 2,3-sigmatropic rearrangement to a dithiocarboxylic acid ester, thereby providing a new carbon–carbon bond synthesis.
