Similarly the substituted decalin 74 was obtained in good yield by the microwave irradiation of 73. The reaction proceeds via an initial Cope rearrangement to generate the allyl vinyl ether 75 for subsequent [3,3]-sigmatropic transformation to ketone 76. Transannular ene cyclization yielded the product 74. ... [Pg.40]

Similar processes have been designed and utilized extensively by Barriault and coworkers for efforts in natural product synthesis. An impressive example of this strategy was utilized for the synthesis of the neo-clerodane skeleton of teucrolivin A. Thermal rearrangement of 92 under microwave irradiation results in a tandem sequence featuring an oxy-Cope rearrangement, followed by the Claisen rearrangement and subsequent ene reaction to give 93.
