The synthesis of β-hydroxy-(E)-vinylstannanes using an in-situ generated cuprate reagent derived from (E)-bis-(tributylstannyl)ethylene

Abstract β-Hydroxy-(E)-vinylstannanes were obtained in good yield by reacting variously substituted terminal epoxides with a higher order cuprate reagent generated “in-situ” by mixing dilithio methyl(thienyl)cyanocuprate ( 6 ) with (E)-bis(tributylstannyl)ethylene ( 5 ).
