摘要：

3-Arylideneflavanones 1-9 were treated with diazomethane. As a result, the following compounds were obtained: the 3-spiropyrazolines (structure A)-2'-phenylchromanone-3'-spiro-3,4-phenyl-1-pyrazoline (1a) and its 3''- and 4''-derivatives (2a-9a), the 4-spiropyrazolines (structure B) 2'-phenylchromanone-3'-spiro-4-1H-5-phenyl-2-pyrazoline (1b) and the 4''-cyano (7b) and 3''-nitro (8b) derivatives; and the methylation product (structure C) 3-(4-N,N-diethyl-amino-beta-methylbenzylidene)flavanone (5c).
