  Stereoselective synthesis of (+)-flutriafol

  摘要：

  The stereoselective synthesis of (+)-flutriafol, a triazole fungicide, has been accomplished in seven linear steps from (1S)-[(4R)-2,2-dimethyl-[1,3]-dioxotan-4-yl]-(4-methoxyphenyl)methanol in 15% overall yield. Diastereoselective nucleophilic 1,2-addition was employed as a key step for constructing the requisite chiral 1,2-diol for flutriafol. A high degree of 1,4-asymmetric induction could be realized via a chelation-controlled mechanism during the key alkylation step. (C) 2008 Elsevier Ltd. All rights reserved.
