“…171 Similar reaction of the oxime dianion derived from 726 with nitriles also led to isoxazole 729 (Scheme 154). 173 Instead of esters 179,[251][252][253][254] and nitriles, also amides and amide derivatives could be used for the synthesis of isox-azoles 735. 255,256 The acylation of dilithiocyclohexanone oxime 733 with excess N,N-dimethylformamide, followed by acid cyclization, gave the desired isoxazole 735 in 87% yield (Scheme 155).…”
