A kinetically controlled diastereoselective cycloaddition between a chiral enol ether and an ortho-quinone methide (o-QM) produces a chroman spiroketal motif that is found in the core of berkelic acid, a novel matrix metalloproteinase (MMP) inhibitor and potent anticancer agent. The transformation lays the groundwork for preparation of future inhibitors aimed at distinguishing among the active sites
手性烯醇醚和邻苯醌甲基化物 (o-QM) 之间的动力学控制的非对映选择性环加成产生了色满螺酮基序,该基序存在于 berkelic 酸、一种新型基质金属蛋白酶 (MMP) 抑制剂和强效抗癌剂的核心中。该转化为未来旨在区分 23 种已知 MMP 活性位点的抑制剂的制备奠定了基础。实验结果表明,环加成产生的立体化学与热力学缩酮化产生的立体化学相反。
