Properties of Amidinated Glucagons [PDF]
European Journal of Biochemistry, 1980 Porcine glucagon has been reacted with a series of alkyl imidates. The ɛ‐amino group and both the α and ɛ‐amino groups were modified and the subsequent glucagon derivatives were purified by ion‐exchange chromatography and characterized. The modified glucagons were compared with native glucagon in their ability to activate hepatic adenylate cyclase and ...

Synthesis and Reactivity of Ynamine Amidines
CHIMIA, 1976 Ynamine amidines can be synthesized from the 1,3-dichlorotrimethine cyanine and primary amines. Ammonia affords the reactive ynamine amidine having a free imino group. This compound cyclises readily with carbon dioxide and phenylisocyanate.

Regiochemistry of cyclocondensation reactions in the synthesis of polyazaheterocycles
Beilstein Journal of Organic Chemistry, 2017 The syntheses of several polyazaheterocycles are demonstrated. The cyclocondensation reactions between β-enaminodiketones [CCl3C(O)C(=CNMe2)C(O)-CO2Et] and aromatic amidines resulted in glyoxalate-substituted pyrido[1,2-a]pyrimidinone, thiazolo[3,2-a ...
