Steric effects in the synthesis of pyrroloindoles from 5-aminoindoles
Yamashkin, S. A.
, p. 47 - 49 (2007/10/03)
The formation of angular pyrroloindoles from 5-aminoindoles substituted in the pyrrole ring depends both on the steric requirements of the substituent at the β-position of the pyrrole ring, and on the structure of the α-hydxyroketone.Significant amounts o
