We have developed efficient methods for the syntheses of 3,5-disubstituted isoxazoles and 1,2,3-triazoles, and 1,3- and 1,4-cycloalkadiene derivatives using polymer-supported selenium resin. The advantages of these methods include straightforward operation, lack of odor, good stability, and high purity of the products.
The monoterpene, trans-p-menth-3-ene-1,2,8-triol, is a naturally occurring alcohol isolated from several herbal plants. In the present work, the asymmetric synthesis of both enantiomers of this natural product was achieved using Sharpless asymmetric dihydroxylation as the key step. A reversal of enantiofacial selectivity was observed in the asymmetric dihydroxylation.
