  • A Lewis Base-catalyzed Hetero Diels–Alder Reaction between Aldehydes and the Danishefsky’s Diene

    DOI:10.1246/cl.2006.328
    日期:2006.3
    A lithium methoxide-catalyzed hetero Diels–Alder reaction of aromatic and aliphatic aldehydes with 1-methoxy-3-trimethylsilyloxy-1,3-butadiene (Danishefsky’s diene) is described. It proceeds through the Mukaiyama-Aldol reaction pathway and affords the corresponding 2,3-dihydropyran-4-one skeletons in good to excellent yields.

  • Asymmetric hetero Diels–Alder reaction using chiral cationic metallosalen complexes as catalysts
    作者:Kohsuke Aikawa、Ryo Irie、Tsutomu Katsuki
    DOI:10.1016/s0040-4020(00)01048-6
    日期:2001.1
    –chromium(III) complexes served as the catalysts for asymmetric hetero Diels–Alder reaction of Danishefsky's diene with aldehydes, achieving high enantioselectivity (up to 97% ee at 0°C). The reactions of aldehydes bearing no precoordinating functional group were well effected by using (R,R)-complexes as catalysts, while those of aldehydes bearing a precoordinating functionality were better effected by
    手性阳离子(R,S)-或(R,R)-(salen)–锰(III)和–铬(III)配合物用作Danishefsky's二烯与醛的不对称杂Diels–Alder反应的催化剂,实现了高对映选择性(0°C时ee高达97%)。通过使用(R,R)络合物作为催化剂,不带有预配位官能团的醛的反应效果良好,而通过使用(R,S)络合物,带有预配位官能团的醛的反应效果更好。
  • Novel Cerium(III)–(<i>R</i>)-BNP Complex as a Storable Chiral Lewis Acid Catalyst for the Enantioselective Hetero-Diels–Alder Reaction

    DOI:10.1246/cl.2003.608
    日期:2003.7
    A novel Ce(III)(R)-BNP complex was conveniently prepared from CAN and (R)-BNP–Na, then successfully used as a homogeneous catalyst for the asymmetric hetero-Diels–Alder reaction affording, after acidic work-up, 6-substituted 5,6-dihydro-4H-pyran-4-one derivatives with high enantioselectivities (up to 94% ee). A mechanistically interesting positive nonlinear effect was also observed.
