Densely functionalized azoxabicyclo[3.3.1]nonanones were prepared by regio- and diastereoselective condensation of 1,1-bis(silyloxy)ketene acetals with isoquinolinium and quinolinium salts and subsequent regioselective and stereospecific iodolactonization.
通过 1,1-双(硅烷氧基)酮乙醛与异喹啉盐和喹啉盐的区域和非对映选择性缩合,以及随后的区域选择性和立体特异性碘内酯化,制备了致密官能化的氮杂环[3.3.1]壬酮。
