One-Flask, Regiospecific Conversions of Allylic Alcohols into Two-Carbon-Extended, Conjugated Dienoate Esters. Use of a New Sulfinyl Orthoester

Sixteen differently substituted primary and secondary allylic alcohols are shown to react with sulfinyl orthoacetate 1 at 100 deg C sequentially via a sigmatropic rearrangement and then a β-elimination of benzenesulfenic acid to form conjugated dienoate esters 5-13 in 45-95percent yields.This one-flask, intramolecular carbon-carbon bond-forming process represents a simple and convenient method for regiospecific γ-attachment of a two-carbon (ethoxycarbonyl)methylene unit via the synthetic equivalent of an SN2' process.Two examples are given in which rationally designed dienoates 20 and 24, prepared via this one-flask process and carrying a pendant alkene unit, undergo intramolecular 2+4 cycloaddition producing bicyclic cyclohexenes 21 and 25.

SYNTHESES AND REACTIONS OF PHENYLTHIO AND PROPYLTHIOACETYLENIC COMPOUNDS

Reactions of 2,2-dichlorovinyl sulfides and their sulfoxide and sulfone derivatives with tert-butoxide and with organolithium compounds have provided entries to chloroethynyl sulides, tert-butoxyethynyl sulfides and their derivatives.Application of these reactions for the synthesis of several functional derivatives is also described.Keywords: 2,2-dichlorovinyl sulfide; chloroethynyl sulfide; tert-butoxyethynyl sulfide; ethynyl sulfide; cyclobutenone
