An improved synthesis of (+)-dehydrobaimuxinol (1), (-)-isobai- muxinol (2) and (-)-baimuxinol (3) (2-hydroxymethyl-6,10,10-trimethyl -11-oxatricyclo[7.2.1.01.6]dodecanes) has been described starting from (-)-Carvone (p-mentha-6,8-dien-2-one) (4). The key step is the regiospecific allylic oxidation of α-agarofuran (7) by selenium(IV) oxide.
描述了一种改进的合成方法,用于合成(+)-去氢白木香醇(1)、(-)-异白木香醇(2)和(-)-白木香醇(3)(2-羟甲基-6,10,10-三甲基-11-氧三环[7.2.1.0^1.6]十二烷),起始材料为(-)-香马轮酮(p-mentha-6,8-dien-2-one)(4)。关键步骤是通过四氧化硒对α-琼脂香烯(7)进行区域特异性的烯丙基氧化。
