Condensation of aldehydes, unsymmetrical disubstituted hydrazines and cyanide resulted in the formation of Mannich bases which, after acylation, formed 6-acylated 3-amino-5-imino oxazolines on acid/acid anhydride treatment. Structure 3 was assigned to these mesoionic compounds on spectral evidence.
醛,不对称二取代肼和氰化物的缩合导致曼尼希碱的形成,该碱在酰化后通过酸/酸酐处理形成6-酰化的3-氨基-5-亚氨基恶唑啉。根据光谱证据,将结构3分配给这些中离子化合物。
