The synthesis of RP 73613 was achieved in 13 steps with an overall yield of 125. The strategy was based on a [3+2] azomethine ylid dipolar cycloaddition to generate the bicyclic framework and the asymmetry was introduced by resolution.
RP 73613的合成分13步完成,总产率为125。该策略基于[3 + 2]偶氮甲亚胺双极性环加成生成双环骨架,并通过拆分引入了不对称性。
