Metallation and funct1onalization of o-sulfonyldi- and o-sulfonyltriarylcarbinols. Unexpectedly facile cyclization of tert-butyl-sulfonylcarbinol into a sultine
摘要:
The lithiation of o-sulfonyltriphenylcarbinols proceeds in the ortho position relative to the sulfonyl group, as indicated by formation of the corresponding carboxylic acids upon the action of CO2. Unusual facility was found for the loss of the tert-butyl group in 2-(tert-butylsulfonyl)-3-diphenylhydroxymethyl-benzoic acid in acid media to give the corresponding sultine.
