Three new fluorenylhydroxamic acids isomeric with the carcinogen N-fluoren-2-ylacetohydroxamic acid have been synthesized by partial catalytic reduction of the corresponding nitrofluorenes, prepared in turn by oxidation of the respective fluorenamines with peroxymaleic acid. A route to N([1-14C]fluoren-1-yl)acetamide and -acetohydroxamic acid by aromatization of the oxime of 3,4-dihydrofluoren-1 (2H)-one
通过部分催化还原相应的硝基芴,合成了三种与致癌物N-芴-2-基乙酰氧肟酸同分异构的新芴基异羟肟酸,而相应的硝基芴又是用过氧马来酸氧化相应的芴胺而制得的。探索了一种通过Semmler-Wolff重排将3,4-二氢芴-1(2 H)-肟肟化的方法,制得N([[ 14 C]芴-1-基)乙酰胺和-乙酰氧肟酸的途径。。通过TLC对产物的分析表明,当在有限量的乙酸酐存在下重排该肟时,亚胺为中间体。
