  Chiral Silver Phosphate-Catalyzed Cycloisomeric Kinetic Resolution of α-Allenic Alcohols

  摘要：

  A kinetic resolution of a-allenic alcohols is realized through chiral silver phosphate-catalyzed cycloisomerization with high stereoselectivity (selectivity factor up to 189) and tolerance of a variety of functional groups. A mechanistic model is proposed to interpret the origin of the high stereoselectivity and broad substrate scope.

  日期：2014.2

  The asymmetric cyclization of 4,4-disubstituted 3-butenoic acids is studied. Amino-thiocarbamates are used as the catalysts and N-bromosuccinimide is used as the stoichiometric halogen source. The resulting gamma-butanolide products are readily converted into the corresponding gamma-butenolides (up to 58% ee) derivatives in one-pot. (C) 2014 Elsevier Ltd. All rights reserved.

• Enantiodivergent syntheses of γ-substituted butenolides with tertiary and quaternary asymmetric centers
  作者：Katsufumi Suzuki、Kohei Inomata

  DOI：10.1016/s0040-4039(02)02711-9

  日期：2003.1

  Continuous nucleophilic addition with several organometallic reagents to tricyclic lactone (-)-1 proceeded diastereoselectively. Newly generated tertiary and quaternary asymmetric centers were controlled by the order in which the nucleophilic reagents were added. Using this methodology, enantiodivergent syntheses of several gamma-substituted butenolides with tertiary and quaternary asymmetric centers were established from a single chiral material.
