Acylation-rearrangement of N-tert-butyl and N-cyclohexyl nitrones of cyclohexanecarboxaldehyde (1), n-butyraldehyde, isobutyraldehyde, 3-cyclohexenecarboxaldehyde, and α-methylpropionaldehyde gave α-pivaloyloxy imines, which underwent reduction with lithi
α-Oxygenation of Aldehydes and Cyclic Ketones by Acylation-Rearrangement of Nitrones
Cummins, Clark H.,Coates, Robert M.
, p. 2070 - 2076 (2007/10/02)
The reaction of N-tert-butylnitrones (1a-e) of aldehydes and N-methylnitrones (2 and 3) of cyclic ketones with acid chlorides in the presence of triethylamine afforded α-acyloxy imines by rearrangement of N-vinyl-O-acylhydroxylamine intermediates.Hydrolysis of the α-acyloxy imines gave α-acyloxy aldehydes and ketones.The acylation-rearrangement reaction offers a new method for α-oxygenation of carbonyl compounds.
