32 - 063A Novel Synthesis of Alkyl, Aryl, Alkenyl, and Alkynyl 1,6-Diketones.— α-Benzotriazole ether moieties are used as acyl anion synthons to synthesizeboth symmetrical and unsymmetrical alkyl, aryl, alkenyl, and alkynyl 1,6-diketones by a lithiation, alkylation, and hydrolysis sequence. The hydrolysis ofthe dibenzotriazole intermediates is performed depending on the substituentsat the two ends either by dilute HCl or using a mixture of oxalic acid, water,and silica gel. — (KATRITZKY, ALAN R.; HUANG, ZHIZHEN; FANG,YUNFENG; PRAKASH, INDRA; J.
