(±)-Isogymnomitrol (1b) and (±)-O-methylgymnomitrol (1c) were synthesized starting from the 1, 2, 6-trimethyltricyclo[5.3.1.02, 6]undecan-9-one derivative 4 via 1, 2-carbonyl transposition from C(9) to C(8) as a key step.
                                    (±)-异球果烷醇(1b)和(±)-O-甲基球果烷醇(1c)是从1,2,6-三甲基
三环[5.3.1.02,6]
十一烷-9-酮衍
生物4出发,通过1,2-羰基转移(从C(9)到C(8))这一关键步骤合成的。
