  Diastereoselectivity in the O-H Insertion Reactions of Rhodium Carbenoids Derived from Phenyldiazoacetates of Chiral Alcohols. Preparation of .alpha.-Hydroxy and .alpha.-Alkoxy Esters

  摘要：

  A series of phenyldiazoacetates 3 derived from enantiomerically pure alcohols ((-)-borneol, (+)menthol, (-)-menthol, (-)-8-phenylmenthol, (-)-trans-2-phenylcyclohexanol, (+)-trans-2-phenyl-cyclohexanol, and (-)10-(dicyclohexylsulfamoyl)-D-isoborneol) were prepared from the corresponding alpha-keto esters 1 by way of the tosylhydrazones 2. Rhodium(II)-catalyzed decomposition of the diazoacetates 3 in the presence of water or alcohols resulted in carbenoid O-H insertion reactions to give the corresponding 2-hydroxy- or 2-alkoxyphenylacetates in good yield, but with varying degrees of diastereoselectivity. A range of rhodium(II) and other metal catalysts were investigated, with rhodium(II) acetate and rhodium(II) acetamide giving the best results. The stereochemistry of the major diastereomer was proved in most cases by independent synthesis from a mandelic acid derivative of known configuration. Possible mechanisms are discussed.

  In the presence of a rhodium catalyst, a chiral glyoxylate hydrate reacts with arylbismuth and aryllead reagents in water and under an atmosphere of air to give the corresponding addition products in high yields. The diastereoselectivities of the reactions were dramatically improved by using water as the solvent. (C) 2002 Elsevier Science Ltd. All rights reserved.
• Diastereoselective reduction of an α-keto-ester derived from (−)-8-phenylmenthol: A 4-step synthesis of R-Halostachine analogue.
  作者：Arlette Solladié-Cavallo、Mohamed Bencheqroun

  日期：1991.1

  An efficient (80% total yield) 4-step synthesis of a 94% e.e. R-(-)-Halostachine analogue is described. The method offers the possibility to introduce various substituents onto the aromatic ring and various alkyl groups on the amine. A one-step and high yield (almost-equal-to 100%) conversion of esters into amides is presented.
