stereogenic center, underwent the highly atrop-stereoselective nine-membered lactone formation with differentiation of the diastereotopic hydroxy groups. Biphenyl-2,6-diols, substituted at the C2′ position with alkanoic acid side chain containing a stereogenic center, underwent the highly atrop-stereoselective nine-membered lactone formation with differentiation of the diastereotopic hydroxy groups.

A C(13)/C(13′) bis-desmethyl analogue of the natural product disorazole Z has been prepared by cyclodimerization through double Stille cross-coupling as the key enabling step. C(13)/C(13′)-Bis(desmethyl)disorazole Z binds to tubulin in a very similar mode as the natural product and inhibits cancer cell proliferation in vitro with low nanomolar potency, thus retaining the potent growth inhibitory capacity
天然产物二唑唑 Z 的 AC(13)/C(13') 双脱甲基类似物已通过双 Stille 交叉偶联作为关键促成步骤,通过环二聚反应制备。C(13)/C(13')-Bis(desmethyl)disorazole Z 以与天然产物非常相似的模式与微管蛋白结合,并在体外以低纳摩尔浓度抑制癌细胞增殖,从而保留了 disorazole 的强大生长抑制能力Z.
