REACTION OF ARYLHYDRAZINES WITH α-FORMYLBUTYROLACTAM DERIVATIVES
Tokmakov, G. P.,Zemyanova. T. G.,Grandberg, I. I.
, p. 47 - 51 (2007/10/02)
The Vilsmeier formylation of butyrolactam and N-phenylbutyrolactam has given their α-dimethylaminomethylene derivatives.The reaction of the latter with α-substituted arylhydrazines leads to the formation of 1-oxo-1,2,3,4-tetrahydro-β-carbolines.When unsub
