The synthesis of optically pure 4,5-dihydro-3(2H)-pyridazinones substituted at C-4, which can be considered conformationally restricted cyclic Glu derivatives, has been accomplished by the asymmetric γ-alkylation of α,β-unsaturated glutamyl sultams under PTC conditions followed by reaction with hydrazines.
光学纯的在C-4处取代的4,5-二氢-3(2 H)-哒嗪酮的合成可以被认为是构象受限的环状Glu衍生物,它是通过α,β-不饱和谷氨酰基的不对称γ-烷基化来完成的在PTC条件下将其与阿片类药物反应,然后与肼反应。
