dienes coupled efficiently in a series of iminonitroso Diels−Alder reactions to produce a series of new spirocyclic adducts. Hydrogenolysis of these adducts afforded new spirocycles that contain multiple handles for further functionalization. Furthermore, stereocontrolled dihydroxylation and reductive cleavage of the spirocyclic adducts generated versatile scaffolds for the syntheses and derivatization
N -Cbz-和Boc-保护的螺环二烯通过环戊二烯的二烷基化制备。这些二烯在一系列亚氨基亚硝基 Diels-Alder 反应中有效偶联,以产生一系列新的螺环加合物。这些加合物的氢解提供了新的螺环,其中包含用于进一步功能化的多个手柄。此外,螺环加合物的立体控制二羟基化和还原裂解为新型螺环碳环核苷类似物的合成和衍生化提供了多功能支架。
