(-)-Agatharesinol dimethyl ether and (-)-sugiresinol dimethyl ether, derivatives of(-)-agatharesinol and (-)-sugiresinol isolated from Agathis australis and Cryptomeria Japonica, respectively were synthesized starting from a protected D-glyceraldehyde in five steps through 1,4-conjugate addition of arylmetal reagents to an alpha,beta -unsaturated ketone.
(-)-Agatharesinol二甲醚和(-)-sugiresinol二甲醚分别是从Agathis australis和Cryptomeria Japonica中分离出的(-)-agatharesinol和(-)-sugiresinol的衍生物。它们的合成以保护的D-甘油醛为起始原料,通过芳基金属试剂对α,β-不饱和酮的1,4-共轭加成,在五个步骤内完成。
