  Features of catalyzed hydration of 2-(dichloromethyl)-N-[(1R)-1-phenylethyl)]cyclopent-3-ene-1-carboxamides

  摘要：

  The hydration of gem-dichloromethyl group in 2-(dichloromethyl)-N-[(1R)-1-phenylethyl)]cyclopent-3-ene-1-carboxamides in aqueous acetonitrile catalyzed by AgNO3, FeCl3 center dot 6H(2)O, PdCl2, and BaO was investigated. The optimum results were obtained at the use of BaO. It was demonstrated, that Pd-catalyzed reactions initiated intermolecular ether formation from the primary hydration products, bicyclic amides.

  Diastereomeric amides produced via the decomposition of easily available (+/-)-7,7-dichlorobicyclo[3.2.0]hept-2-en-6-one by treatment with (+)- or (-)-alpha-methylbenzylamines were transformed into bicyclic lactam-aminals, which can easily be separated using the column chromatography on SiO2. The latter products lead to enantiomeric 3-oxabicyclo[3.3.0]oct-6-en-2-ones after the removal of the chiral auxiliary. Crown Copyright (C) 2008 Published by Elsevier Ltd. All rights reserved.
