Addition of the lithium ester enolates to 1-chlorovinyl p-tolyl sulfoxides, which were synthesized from chloromethyl p-tolyl sulfoxide and ketones or aldehydes, gave esters having a tertiary or a quaternary carbon at the 3-position, and chlorine and sulfinyl groups at the 4-position in high to quant
