Synthese und Photoisomerisierung von sterisch gehinderten 2,6-Dialkylpyridin-N-oxiden

Synthesis of the new sterically hindered pyridine-1-oxides 2c and 6a-c is described.Copper(II)-catalyzed photolysis of 2 and 6a in aqueous medium provides only small amounts of 2-acylpyrroles 8 and 10a together with by-products.Exclusive formation and better yields of 10 can be received upon irradiation of 6 in none protic solvents at low temperature.Introduction of bulky substituents as in 6 failed to stabilize any of the postulated intermediates in order to be identified during photoreaction.It is assumed that the high rate of polymerization is caused by unstable 1,3-oxazepines like 13.

Intramolecular Thermal Oxidoreduction of N-(2-Hydroxypropyl)-β-enaminoesters: Synthesis of N-(Acetonyl)-β-enaminoaldehydes and 2-Acetylpyrroles

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.
