  (+)-NLEs, have been detected in the Ti(IV)/BINOL complex-mediated catalytic asymmetric aldol reaction of three different masked acetoacetate esters. The use of a different procedure for the catalyst preparation disclosed the occurrence of aldol condensation of Chan's diene through an auto-inductive process.

• A Study Directed to the Asymmetric Synthesis of the Antineoplastic Macrolide Acutiphycin under Enantioselective Acyclic Stereoselection Based on Chiral Oxazaborolidinone-Promoted Asymmetic Aldol Reactions

  日期：1999.7.1

  A shortening of the reaction path can be realized by using a series of the chiral oxazaborolidinone-promoted aldol reaction with respect to the practical synthesis of the (+)-acutiphycin seco acid derivative 5. The linear strategy is based on the utilization of five aldol reactions with a sequence of silyl nucleophiles, 7, 8, 35, 10, and 11, in the presence of stoichiometric amounts of the promoter, 1 or 2. The construction of the relative configuration between the stereogenic centers is diastereoselectively controlled by the stereochemistry of the promoter used in the enantioselective aldol reaction, which is nearly independent of that of the substrate (promoter control).

  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.

  日期：2006.12

  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.
