The invention discloses a method for synthesizing 1-tosyl-2-vinyl-1 hydro-pyrrole. The method is mainly characterized in that: (1) a non-transition metal is adopted for catalyzing; (2) 1-acetenyl-4-alkenyl iodide is taken as a raw material for synthesizing; (3) a reaction is performed at a low temperature; (4) the reaction is completed at one step; (5) the produced product takes the 1-tosyl-2-vinyl-1 hydro-pyrrole as a main structure; (6) the physical and chemical properties of the produced products cannot change in a normal-temperature and high-temperature environment; (7) other by-products are not produced in the reaction.
