  1.3-Bis-(trimethylsilyloxy)-1-methoxy-buta-1,3-diene (Chan's diene) can be conveniently used in asymmetric aldol reaction with aromatic, heteroaromatic, alpha,beta -unsaturated and aliphatic aldehydes in the presence of catalytic amounts (2-8% mol) of chiral Ti(IV)/(R)-BINOL complex.

  Chiral delta-hydroxy-delta-ketoesters are easily available through the enantio selective vinylogous aldol reaction of Chan's diene promoted by a SiCl4/chiral phosphoramide catalytic system. The procedure is conveniently exploited for a very rapid approach to (+)-kavain, a natural bio-active alpha-pyrone compound. (c) 2007 Elsevier Ltd. All rights reserved.
• Solvent-free asymmetric vinylogous aldol reaction of Chan's diene with aromatic aldehydes catalyzed by hydrogen bonding

  日期：2009.7

  Chan's diene proved to react with aromatic aldehydes under organocatalytic conditions in presence of a chiral naphthyl-TADDOL derivative to give vinylogous aldols (up to 65% ee) with complete gamma-selectivity. A further process of hetero-Diels-Alder cycloaddition, leading to chiral pyran-4-one derivatives (up to 60% ee), was favoured by electron-withdrawing substituents on the aromatic ring.

  A simple and convenient method was reported for the preparation of optically active beta-hydroxy-beta-arylpropionates, delta-hydroxy-delta-aryl-beta-oxo-pentanoates and their butyryl derivatives via CRL-catalyzed hydrolysis. The optically active products are potential precursors of some chiral pharmaceuticals and natural products. (C) 2005 Elsevier Ltd. All rights reserved.
