Intramolecular thermal oxidoreduction of N-(2-hydroxypropyl)-β-enaminoesters: synthesis of N-(acetonyl)-β-enaminoaldehydes and 2-acetylpyrroles
Abstract
Flow pyrolysis of the β-enaminoesters (1) provides the enaminoaldehydes (2), resulting from intramolecular oxidoreduction, and the acetylpyrroles (3); their relative yields depend on the temperature range.
