REACTIONS OF ARYLHYDRAZINES WITH α-FORMYL DERIVATIVES OF SIX- AND SEVEN-MEMBERED RING LACTAMS
Tokmakov, G. P.,Grandberg I. I.
, p. 1160 - 1165 (2007/10/02)
Reactions of α-formyl derivatives of N-methyl-δ-valerolactam and N-methyl-ε-caprolactam with arylhydrazines lead to the formation of 3,4,5,10-tetrahydroazepinoindole-1(2H)-one and 2,3,4,5,6,11-hexahydro-1H-azocinoindol-1-one derivatives.As t
