The azabicyclic moiety present in tropane alkaloids can be conveniently synthesized in high yield on solid phase using a modification of Robinson's tropinone synthesis.1 The ε-amino group on a lysine residue attached to Tentagel® resin was treated with 10 eq excess of succinic dialdehyde and 1 eq of acetonedicarboxylic acid for 12 hours with a citric acid buffer of pH 4 as solvent, resulting in the
托宾生物碱中存在的氮杂双环部分可通过罗宾逊(Robinson's)肌钙蛋白合成的修饰方便地在固相上以高收率合成。1附连到的Tentagel的ε氨基上的赖氨酸残基组®树脂用10个当量过量琥珀酸二醛和1个当量丙酮二羧酸的12小时与作为溶剂的pH 4的柠檬酸缓冲液处理,从而导致的一个形成赖氨酸的ε-氨基上的8-氮杂双环[3.2.1]辛烷结构产率为93%。
