(2R, 3R)-dihydroxy-tetrahydronaphthalene 4 has been prepared via an efficient three-step synthesis from cis-(1R, 2S)-dihydroxy-1,2-dihydronaphthalene 1. The latter was obtained by bioconversion of naphthalene by a modified strain of Pseudomonas fluorescens. The diol 4 has been successfully tested in a conjugate asymmetric addition of lithium dibutyl cuprate to the monocrotonate 7. Copyright (C) 1996 Elsevier Science Ltd
(2R,3R)-二羟基四氢
萘4是通过从顺式-(1R,2S)-二羟基-
1,2-二氢萘1出发,经过高效的三步合成制得的。顺式-(1R,2S)-二羟基-
1,2-二氢萘1则是通过对一株改良的Pseudomonas fluorescens菌株进行
萘的
生物转化获得的。二醇4在联烯不对称加成反应中,与二丁基
铜锂和单甲基Crotonate7的反应中取得了成功。版权 © 1996 Elsevier Science Ltd
