One-Pot Synthesis of 2,4-Benzodiazepin-1-ones Using Benzotriazole Methodology
摘要:
2, 4-Benzodiazepin-1-ones were prepared in moderate to good yields by reaction of bis(benzotriazolylmethyl)amines with ortho-metalated N-substituted benzamides.

3-dienes and Cp2TiH, react with benzotriazole derivatives to give homoallylic amines in good yields. Under similar conditions, triple cascade reactions (allyltitanation followed by cationic 2-aza-Cope rearrangement followed by a second allyltitanation) occur from bis(benzotriazolyl) compounds affording a straightforward route to homoallyl-(E)-homocrotylamines. A theoretical study provides further insight

the amine, and is also influenced by the nature of the solvent. Primary aliphatic 1,2- or 1,3-diamines yield cyclic aminals which are imidazolidine (8a) and hexahydropyrimidine (8b) derivatives. Reactions of these aminals with Grignard reagents, and with cyanide anion as nucleophiles, are also described.
