An efficient synthesis of 1,3-cyclohexadienes from oxabicyclo[2.2.1]heptenes via tandem ring opening-Peterson elimination reactions
摘要:
Oxabicyclo[2.2.1]heptenes react with PhMe2SiLi or PhMe2SiCu.LiCN to yield 1,3-cyclohexadienes. The reaction pathway is shown to proceed via an addition-elimination-Peterson olefination sequence.
