A Novel Synthesis of α-Tellanyl α,β-Unsaturated Aldehydes Using α-Tellanyl
Lithiums. — The α-phenyltellanylvinyl lithium (II) is generated in
33- 198 β-Alkoxyalkenyl
situ and undergoes methylation or nucleophilic addition with aldehydes and ketones.
The successive dehydration of the allylic alcohols (VI) thus obtained with Tms-O-Tf
affords the title compounds, which are transformed into various useful compounds.
