Asymmetric Heck reaction of alkenyl iodides in the presence of silver salts. Catalytic asymmetric synthesis of decalin and functionalized indolizidine derivatives
Decalin derivatives 3 (up to 80% ee) and indolizidine derivative 6 (up to 86% ee) have been synthesized by an asymmetric Heck reaction starting with prochiral alkenyl iodides 1 and 4, respectively. The important role of silver salts in the asymmetric Heck reaction is discussed, and the conversion of 6 to δ-coniceine (24) is also described.
