DABCO-catalyzed reactions of hydrazones with activated olefins

, p. 7277 - 7288 (2007/10/03)
This paper describes several highly efficient DABCO-catalyzed aza-Michael addition reactions of hydrazones to activated olefins. In most cases, these aza-Michael addition reactions gave the corresponding products in high yields under mild conditions. The plausible reaction mechanism is discussed on the basis of deuterium labeling experiments. Upon treatment with HCl, the corresponding cyclized products can be obtained in high yields from the Michael addition products.

The previously reported synthesis of 3,4-dihydro-2-tosyl-1,2-diazepines by the acid-catalysed reactions of p-toluenesulphonylhydrazide with αβ,γδ-unsaturated ketones has been extended to other 2-substituted analogues (3) by the use of a variety of hydrazi
