In addition, in the preparation method of the dihydro-1H-phosphole 1-oxide derivative according to the present invention, diverse phosphinine oxide derivatives may be prepared with high yield by a simple synthetic process through reacting a phosphinic derivative and a vinyl derivative in the presence of a rhodium (Rh) catalyst, an oxidizing agent and a base.
Abstract:
The present invention relates a method for manufacturing alkenyl triflate derivatives represented as chemical formula 1. The manufacturing method of the present invention has benefits not only to reduce reaction byproducts through addition reaction of tribonding derivatives and trifluoro methane sulfonate but also to streamline reaction steps to one step and to manufacture alkenyl triflate derivatives in high yield.
Abstract:
The present invention relates to an enyne derivative represented by chemical formula 1 and a manufacturing method thereof and, more specifically, to a method for selectively manufacturing an enyne derivative with high yield by performing cross coupling reactions on halide derivatives and organic indium reagents produced in situ by making vinyl propargyl halide derivatives react with indium (In) under presence of palladium catalysts and to a novel enyne derivative manufactured by the method. (In chemical formula 1, R_1 and R_2 are the same as defined in the detailed prescription of the present invention.)
