A second-generation synthesis of three structurally related chlorosulfolipids has been developed. Key advances include highly stereocontrolled additions to α,β-dichloroaldehydes, kinetic resolutions of complex chlorinated vinyl epoxide intermediates, and Z-selective alkene cross metatheses of cis-vinyl epoxides. This strategy facilitated the synthesis of enantioenriched danicalipin A, mytilipin A,
已开发出三种结构相关的氯硫脂的第二代合成方法。主要进展包括对 α,β-二氯醛的高度立体控制添加、复杂氯化乙烯基环氧化物中间体的动力学分辨率以及顺式乙烯基环氧化物的Z-选择性烯烃交叉复分解。该策略分别通过 9、8 和 11 个步骤促进了对映体富集的 danicalipin A、mytilipin A 和 malhamensilipin A 的合成。

Copper iodide and weakly ligated palladium complexes PdCl2(RCN)(2) (R = Ph, Me) catalyzed efficiently the coupling reaction of vinyl chlorides with 1-alkynes in the presence of piperidine to give the corresponding conjugated enynes in good to excellent yields. The reaction takes place rapidly and cleanly at room temperature. Application to the synthesis of terbinafine which exhibits strong antimycotic activity has been realized.
