affords cis-1,2-dihydroxycyclohexa-3,5-diene (2) which may be converted in five steps and 49% overall yield to (±)-pinitol. Resolution of an intermediate alcohol (6) with menthoxyacetyl chloride provides optically pure materials which may be independently transformed to (+)- or (−)-pinitol. Demethylation conditions for pinitol together with further reactions of (2) and related compounds were investigated
用恶臭假单胞菌(Pseudomonas putida)对苯进行微生物氧化可得到顺式-1,2-二羟基环己-3,5-二烯(2),可以分五个步骤进行转化,总产率为49%,为(±)-松醇。用薄荷醇乙酰氯拆分中间体醇(6)可提供光学纯的物质,可将其独立转化为(+)-或(-)-松醇。研究了松醇的脱甲基条件,以及(2)和相关化合物的进一步反应。
