  Transmissive Olefination Route to Putative “Morinol I” Lignans

  摘要：

  A series of morinol-type lignans were rapidly assembled using a Grignard-based transmissive olefination. In combination with palladium-catalyzed arylations, the strategy provides stereoselective access to (7Z,7'E), (7E,7'E), and (7E,7'Z) morinol diastereomers and the (7Z,8'E) and (7E,8'E) conjugated analogues. Critical for the E/Z stereoselectivity is a new, general method for converting alkenenitriles to alkenemethanols that circumvents the enal E/Z isomerization commonly encountered during conventional i-Bu2AlH reduction.
