Organotellurides as a source of organometallics:application in the synthesis of (+/-)-frontalin

摘要

A masked lithium homoenolate,generated by tellurium/lithium exchange,was reacted with epoxides.The lithium compound was also converted into other organometallics such as Grignard,and cuprates and the reactivity of those organometallics with epoxides was evaluated.The same building block was employed in the synthesis of (+/-)-frontalin.
