  • Enantioselective Synthesis of Fused Cycloheptadienes by a Tandem Intramolecular Cyclopropanation/Cope Rearrangement Sequence
    作者:Huw M. L. Davies、Brian D. Doan
    DOI:10.1021/jo990888d
    日期:1999.11.1
    The asymmetric induction in the intramolecular cyclopropanations of allyl vinyldiazoacetates catalyzed by tetrakis[N-[4-dodecylphenyl)sulfonyl]-(S)-prolinato] dirhodium [Rh-2(S-DOSP)(4)] is very dependent on the allyl substitution pattern. The reactions of cis-alkenes result in much higher asymmetric induction than trans-alkenes while the highest enantioselectivity was obtained with a disubstituted terminal alkene. The intramolecular cyclopropanation of dienylmethyl vinyldiazoacetates results in the synthesis of fused cycloheptadiene ring systems with full control of relative stereochemistry and variable enantioselectivity. The synthetic utility of this process was demonstrated by a short synthesis of 5-epi-tremulenolide in 93% ee.
  • Asymmetric synthesis of the tremulane skeleton by a tandem cyclopropanation/cope rearrangement
    作者:Huw M.L. Davies、Brian D. Doan
    DOI:10.1016/0040-4039(96)00723-x
    日期:1996.6
    A highly diastereoselective and enantioselective 3 + 4 annulation method for the synthesis of polycyclic systems was achieved in a two step sequence consisting of an asymmetric intramolecular cyclopropanation catalyzed by dirhodium(II) tetrakis((R)-N-(p-(dodecyl)phenylsulfonyl)prolinate) followed by a Cope rearrangement of the resulting divinylcyclopropane intermediate.
