  Modified Monoterpenes from Biotransformation of (−)-Isopiperitenone by Suspension Cell Culture of Mentha piperita

  摘要：

  The biotransformation of (-)-(4R)-isopiperitenone (1) by suspension cell culture of Mentha piperita yielded three new hydroxylated derivatives, 4-6, and two new epoxidized derivatives, 7 and 8. (-)-7-Hydroxyisopiperitenone (2) and its glucoside were previously isolated from the culture. The structures of 4-8 were elucidated using spectral methods, and their absolute stereochemistry was established by NMR experiments and correlation with compounds of known configuration.

  The impregnation of Cr-III(salen) complexes on silica resulted in a heterogeneous catalyst for the asymmetric ring opening (ARO) reaction of epoxides with good selectivity and acceptable activity. As became apparent from a series of 10 successive batch tests in the ARO reaction of 1,2-epoxyhexane, leaching was limited, while catalytic activity and selectivity were acceptable. Though the support suffered from abrasion in the batch reactor, 80% of the catalyst was easily recoverable via simple extraction from the used solid catalyst and entirely transferable onto a fresh carrier via impregnation. It was shown that 80% of the leached catalyst at the end of the tests could be transformed into a fresh heterogeneous catalyst as well. (C) 2003 Elsevier Ltd. All rights reserved.
