The divergent synthesis of penaresidin B and its straight side chain analogue was accomplished by constructing an azetidine ring via SN2 type cyclization of protected 2,3-syn-3,4-syn-4-amino-1,3-dihydroxyhept-6-en-2-yl mesylate and late-stage introduction of an alkyl side chain via olefin cross-metathesis of 4-allylazetidine with readily available terminal alkenes. This synthetic route would be useful
Penaresidin B及其直链类似物的发散合成是通过受保护的2,3- syn -3,4- syn -4-氨基-1,3-dihydroxyhept-6的S N 2型环化构建氮杂环丁烷环而完成的-甲-2-烯基磺酸酯和经由4-烯丙基t啶的烯烃与易得的末端烯烃的交叉复分解作用的烷基侧链的后期引入。该合成路线将对合成Penaresidin侧链类似物有用。

The preparation of substituted azetidines and larger ring, nitrogen-containing saturated heterocycles is enabled through efficient and selective intermolecular sp3-C-H amination of alkyl bromide derivatives. A range of substrates are demonstrated to undergo C-H amination and subsequent sulfamate alkylation in good to excellent yield. N-Phenoxysulfonyl-protected products can be unmasked under neutral

A novel and efficient asymmetricsynthesis of the potent actomyosin ATPase activator, penaresidin B, is described in a short and complete stereoselective manner by featuring the elaboration of the fully functionalized homochiral lactam, which can also be regarded as an advanced intermediate for the synthesis of other azetidine alkaloids.
