The enantiomerically pure methyl ester of the complete larger hydroxy acid (C(1)C(18)) of the macrodiolide antibiotic pamamycin-607 has been synthesized using a general sultone route to actic acids and analogs. The requisite N,N-dimethylamino moiety was introduced by Mitsunobu inversion with hydrazoic acid followed by a reaction cascade involving hydrogenation and double reductive methylation.
大环内酯抗生素pamamycin-607的完整较大羟基酸(C(1)C(18))的对映体纯甲酯已使用一般的磺内酯路线合成了乳酸和类似物。必需的N,N-二甲基氨基部分是通过用肼酸进行Mitsunobu转化而引入的,随后是涉及氢化和双还原甲基化的反应级联。
