The lactonization of hydroxy esters was performed over hydrous zirconium(IV) oxide modified by trimethylsilyl chloride.In the case of both primary and secondary hydroxy esters, lactones were obtained in high yield.In addition, it was elucidated that modified-hydrous zirconium(IV) oxide is superior to hydrous zirconium(IV) oxide regarding selectivity in lactonization.

The development of 1,5-dimethyl-9-azanoradamantane N-oxyl (DMN-AZADO; 1,5-dimethyl-Nor-AZADO, 2) as an efficient catalyst for the selective oxidation of primary alcohols in the presence of secondary alcohols is described. The compact and rigid structure of the azanoradamantane nucleus confers potent catalytic ability to DMN-AZADO (2). A variety of hindered primary alcohols such as neopentyl primary alcohols were efficiently oxidized by DMN-AZADO (2) to the corresponding aldehydes, whereas secondary alcohols remained intact. DMN-AZADO (2) also has high catalytic efficiency for one-pot oxidation from primary alcohols to the corresponding carboxylic acids in the presence of secondary alcohols and for oxidative lactonization from diols.

A catalytic amount of TEMPO in the presence of PhI(OAc)2 effected oxidative lactonization of 1,6- and 1,7-diols, directly affording seven- and eight-membered lactones, respectively, in good yields. The Royal Society of Chemistry 2010.
