30.3.6.1.6 Method 6: Sulfanylation (Thiolation) Reaction of α-Sulfonyl Carbanions

DOI: 10.1055/sos-SD-030-00335

Ogura, K.Science of Synthesis, (200730455.

The α-sulfanylation of a sulfone was first reported in connection with a synthesis of taxane; thus, when either of the tricyclic hydroxy sulfones 34A or 34B is treated with potassium hydride, deprotonation is accompanied by ring opening to produce a bicyclic salt 35 that is α-sulfanylated in situ by the addition of 1,2-dimethoxyethane to give the ketone 36 (Scheme 14).[‌30‌]
