3,3-Dimethyl-2-phenyl-cyclopropenecarboxylic acid 4 is prepared, starting with chlorophenyldiazirine 1. With acids 4 yields the open chain carboxylic acids 5, 6 and 7. Thionychloride leads to the cyclobutenone 10, DCC to the acid anhydrides 11 and 13.
由氯苯基二嗪1开始制备3,3-二甲基-2-苯基-环丙烯羧酸4。用酸4产生开链羧酸5、6和7。亚硫酰氯生成环丁烯酮10,DCC生成酸酐11和11。 13
