We present here the 1 H, 13 C, and 15 N NMR comparative studies of nitrosubstituted 1,2phenylenediamines , that were prepared by some of us [5,6] in view of their potential synthetic . An efficient synthesis of medium-sized heterocyclic rings was achieved using a one-pot aza-Wittig/retro-aza-Claisen sequence of vinyl cyclobutanecarboxaldehydes derived from simple allylic carbonates. The use of various Staudinger reagents in the aza-Wittig reaction allows for a variety of N-substituted products to be obtained. The rearrangement is under thermodynamic control driven by relief Cited by: Synthetic and Natural Phenols - Ebook written by J.H.P. Tyman.

Synthetic photochemistry deals with electronically excited molecules and the chemical processes induced by light (Box 1). 1 Since the chemical reactivity of excited molecules differs fundamentally from that in the ground state, 2 light‐mediated chemistry has the potential to unlock reaction manifolds that are unavailable to conventional ground‐state pathways. It plays a central role in biochemistry, organic synthesis, coordination chemistry, homogeneous catalysis, solid state chemistry, and material sciences. Heterocyclic chemistry is underdeveloped. The research began only in with the discovery of the McCormack reaction,.Since then the research in this field has been growing at a slow, but. Here’s a process that I think needs continued attention from the synthetic community: Making saturated nitrogen heterocycles from simple N-alkylamines by intramolecular CH amination reactions. There’s a lot of great chemistry out there for related process where there is an electron-withdrawing group attached to the nitrogen within the tether (vide infra), but let’s focus on N-alkyl groups.
