Combining an efficient preparation of cyclobutenylmetal species, high-yielding cross-coupling reactions, and highly diastereoselective [4 + 2]-cycloaddition led to opening a new route toward the synthesis of fused alkylidenecyclobutanes containing up to five consecutive stereocenters. New complex architectures, analogues to protoilludane skeletons, were obtained in a very efficient manner and with
结合高效地制备环丁烯基金属物质,高产率的交叉偶联反应和高度非对映选择性的[4 + 2]-环加成反应,为合成包含多达五个连续立体中心的亚烷基环丁烷烃开辟了一条新途径。从商业来源开始,以非常有效的方式并以最少的步骤获得了新的复杂结构,类似于原芥酸烷骨架,并测试了其对白血病细胞系HL60的细胞毒性。
