以中间体1-烯丙基-2，3，3-三甲基吲哚碘化物与5-硝基水杨醛等为主要试剂，通过两种不同路线合成了题示化合物，并通过1HNMR和IR确证了目标产物的结构。对分步合成路线和以哌啶为催化剂的“一锅法”合成路线进行对比，选择了较优合成路线。
The title compound,1-allyl-6′-nitrio-indolino-spiropyran was synthesized using intermediate 1-allyl-2,3,3-trimethyl-indolenium iodide and 5-nitrosalicylaldehyde as main regents by two different synthesis routes.The structure of title compound was characterized by 1HNMR and IR.The "one-pot"synthesis route which using piperidine as catalysis was compared with the step-by-step synthesis route which using no piperidine.The better synthesis route with the higher yield was given.
