This work reports two efficient pathways for the rapid preparation of over 20 structurally diverse BCB ketones, encompassing simple alkyl and aryl derivatives, as well as unprecedented amino acid, dipeptide, bioisostere, and bifunctional linchpin reagents currently inaccessible using literature methods. Analogues are readily forged in two steps and in high yields from simple carboxylic acids or through
双环[1.1.0]丁烷(BCB)是高度应变的碳环,已作为通用的合成工具出现,特别是用于功能化小分子的构建。这项工作报告了两种快速途径,可以快速制备20多种结构多样的BCB酮,包括简单的烷基和芳基衍生物,以及前所未有的氨基酸,二肽,生物等排物和双官能化的Linchpin试剂,目前尚无法通过文献方法获得。从简单的羧酸或通过不对称的酮合成开始,以方便的羰基取代等价物,可以很容易地分两步以高收率生产类似物。强调了这种新的应变亲电试剂盒对蛋白原性亲核试剂的选择性修饰的实用性。
