  Synthesis of highly oxygenated enantiomerically pure cis-bicyclo[4.3.0]nonanes from secondary sugar allyltin derivatives

  摘要：

  Secondary sugar allyltin derivatives of the D-series: Sug-CH(SnBu3)-CH=CH2 (obtained in an S(N)2' reaction of the corresponding primary allylic mesylates with 'Bu3SnCu') with the S-configuration at the stereogenic center bearing the -SnBu3 group decompose at 140degreesC to dienoaldehydes: CH2=CH-CH=CH-[(CHOR)(3)]-CHO with the cis geometry across the internal double bond. Such aldehydes react with the stabilized Wittig reagents to afford trienes, cyclization of which provides highly oxygenated enantiomerically pure cis-bicyclo[4.3.0]nonenes. This methodology is complementary to that recently proposed by us leading to such bicyclic systems, but with the trans junction between the five- and six-membered rings.

  Stability of regioisomeric sugar allyltins. Cleavage of the carbon oxygen bond under radical conditions

  摘要：

  Secondary sugar allyltin derivatives [Sug-CH(SnBu3)-CH=CH2] decompose at high temperature (140 degreesC) with elimination of the tin moiety and opening of the sugar ring. The cis-dienoaldehydes thus formed react with Ph3P=CH-CO2Me to afford the corresponding trienes, which spontaneously undergo stereoselective intramolecular [4+2] cycloaddition to optically pure, highly oxygenated bicyclo[4.3.0]nonene derivatives. Primary sugar allyltins [Sug-CH=CHCH2-SnBu3] are thermally stable and do not decompose up to 170 degreesC. (C) 2001 Elsevier Science Ltd. All rights reserved.
