Abstract

Abstract An update of our preliminary communication concerning an efficient organocatalytic procedure for the transfer of tin onto aldehydes is presented. This update combines (i) a full study of the preparation of γ-silyloxyallylstannanes from β-substituted enals,(ii) a “one-pot” sequence (in inter-and intramolecular version) including N-heterocyclic carbene (NHC)- catalyzed silylstannation reaction/Lewis acid-promoted allylstannation reaction to furnish ...
