摘要：

When 3-phenyl-l-menthopyrazole was used as a chiral auxiliary, the diastereomeric preparation of alpha- and beta-phenylthio-substituted N-acylpyrazoles (4 and 9) was accomplished in high yield by the alpha-sulfenylation using diphenyl disulfide and the conjugate addition of thiophenol, respectively.
