An optically active 1,2-homoheptafulvalene was successfully synthesized and subjected to spectroscopic investigation. The cycloaddition of the optically active hydrocarbon with tetracyanoethylene (TCNE) and 4-phenyl-1,2,4-triazoline-3,5-dione(PTAD) gave a [4 + 2] cycloadduct and a mixture of [8 + 2] cycloadducts, respectively, which are both optically active.
光学活性的1,2-高庚基富瓦烯已成功合成,并进行了光谱研究。光学活性烃与四氰基乙烯(TCNE)和4-苯基-1,2,4-三唑啉-3,5-二酮(PTAD)的环加成反应得到[4 + 2]环加合物和[8 + 2]的混合物各自具有光学活性的环加合物。
