Studies on the Oxidation of Enamines with Molecular Oxygen. III Oxidation of Some Amino Styrenes

, p. 455 - 466 (2007/10/02)
In the oxidation of the amino styrenes 1a - 1j only products of the oxidative attack at the C=C double bond and hydrolysis products are obtained.Aprotic dipolar solvents and the addition of molecular sieve 5A promote the oxygen uptake.The addition of hydroquinone to the oxidation system does not influence the rate of oxygen absorption or the yields of the oxidation products.
Improved Titanium Tetrachloride Procedure for Enamine Synthesis.II.Scope of the Reaction

The scope of enamine formation by a procedure where the carbonyl compound is added to a preformed titanium tetrachloride-amine complex was investigated with a series of different types of carbonyl compounds and two secondary amines (morpholine and pyrrolidine).The carbonyl compounds include aldehydes, cyclic ketones and some substituted aryl alkyl ketones.Yields of isolated products were in the range 67-100 percent with the exception of the pyrrolidine enamine from camphor which gave 53 percent of the isolated product.
