Oxoammonium salts. 9. Oxidative dimerization of polyfunctional primary alcohols to esters. An interesting β oxygen effect

The use of the oxidant 4-acetylamino-2,2,6,6-tetramethylpiperidine-1- oxoammonium tetrafluoroborate in combination with pyridine for the oxidative, dimeric esterification of primary alcohols is described. The ester is the predominant product of the reaction with alcohols containing a β oxygen. In the absence of a β oxygen, the corresponding aldehyde is found in appreciable amounts, but a concentration effect can be observed. In the absence of pyridine, little ester is formed, and no appreciable reaction takes place with β-oxygenated compounds. δ Lactones have been prepared from diethylene glycol and 2,2′-thiodiethanol, without sulfur oxidation.
Preparation and Stability of 1,4-Oxathian-2-ones
Koskimies, Jorma K.
, p. 101 - 108 (2007/10/02)
Several methods of preparation of various substituted 1,4-oxathian-2-ones are described, including the acid-catalyzed ring closure of δ-hydroxy acids, prepared via α-halo ketones or α-halo acids, and the base-catalyzed ring closure of β-haloethyl thioglycolate. 1,4-Oxathian-2-one is completely hydrolyzed in D2O to the hydroxy acid at a rate comparable to the hydrolysis of δ-valerolactone.The rate of the lactonization is estimated to be ca. 100 times smaller in oxathianone than in valerolactone.
