Aldehydes as Photoremovable Directing Groups: Synthesis of Pyrazoles by a Photocatalyzed [3+2] Cycloaddition/Norrish Type Fragmentation Sequence

A straightforward methodology for the regioselective synthesis of pyrazoles has been developed by a domino sequence based on a photoclick cycloaddition followed by a photocatalyzed oxidative deformylation reaction. Distinguishing features of this protocol include an unprecedented photoredox-catalyzed Norrish type fragmentation under green-light irradiation and the use of α,β-unsaturated aldehydes as synthetic equivalents of alkynes, where the aldehyde is acting as a novel photoremovable directing group.

The Rotation-dominated Ring Inversion/Nitrogen Inversion/Rotation Process in N-Acyloxy-2,2,6,6-tetramethylpiperidines. A Dynamic NMR Study

The temperature dependence of the NMR spectra of a series of N-acyloxy-2,2,6,6-tetramethylpiperidines is reported and discussed in terms of a conformational process which involves ring inversion, nitrogen inversion and rotation about the nitrogen-oxygen bond.Nitrogen inversion contributes ca. 11 kcal mol-1 to the observed barriers, so in the compounds with higher barriers, steric interaction of the acyl and methyl groups during rotation determines the barrier height.
