A influencia de grupos protetores na sintese regio- e estereosseletiva de teluretos vinilicos preparados a partir de BuTeNa e alcoois propargilicos e homopropargilicos demonstrou que o eter de silicio TIPS e util como grupo regio-dirigente. A aplicacao da metodologia na sintese de um fragmento do (±)-Seselidiol, um produto natural, demonstrou a aplicabilidade da metodologia desenvolvida. The influence of protecting groups on the synthesis of regio- and stereodefined vinyl tellurides derived from the reaction of BuTeNa and propargylic- or homo-propargylic alcohols showed that TIPS silyl ether is useful as a regiodirecting group. The application of the methodology to the synthesis of a fragment of (±)-Seselidiol, a natural product, demonstrated the applicability of the new methodology.
