  Telluro-directed regiospecific and highly stereoselective reaction of ethyl 5-telluro-(2E,4Z)-pentadienoate with organocopper reagents

  摘要：

  Ethyl 5-telluro-(2E,4Z)-pentadienoate 2, which is prepared by the Wittig olefination of (Z)-beta-telluroacrolein 1, reacted very rapidly with organocuprates 3 at -78 degrees C to form exclusively the corresponding 5-substituted products 4 with high stereoselectivity and in excellent yields.
