The thermal reaction of 1-cyano-2-methyl-3,4-dihydro-2-thianaphthalene() in toluene afforded 1-benzyl-1-cyano-2-thiochroman() together with 1-cyano-1-methyl-2-thiochroman(), whereas the thermal reaction in ethanol gave the spiro-compound() in 82.7% yield. The structure of the spiro-compounds was established by their spectral data and chemical reactions.
1-氰基-2-甲基-3,4-二氢-2-噻吩并(t )在甲苯中的热反应得到1-苄基-1-氰基-2-噻吩并(1-氰基-1-甲基-2) -thiochroman(),而在乙醇中的热反应以82.7%的收率得到螺-化合物()。螺环化合物的结构由其光谱数据和化学反应确定。
