Conformation and Crystal Structure of Dipyrrinones with Oxindole Components

Boiadjiev, Stefan E.,Lightner, David A.

, p. 489 - 499 (2003)

Pyrrole α-aldehydes (2-formyl-4,5-dimethyl- 1H-pyrrole and 2-formyl-N-methylpyrrole) condense readily at C(3) of indolin-2-ones to give dipyrrinone analogs, such as (3Z)-[(4,5-dimethylpyrrol-2-yl)-methylidenyl]- indolin-2-one and (3E)-[(1-methylpyrrol-2-y
