Synthesis of aryl allyl alkynes via reaction with allyl amine and aryl alkynoic acids through decarboxylation

Abstract

Allyl alkynoic esters were synthesized by the reaction of allyl amines and alkynoic acids via deaminative esterification. The reaction of allyl alkynoic esters with Pd(dba)₂ and Xantphos in digylme at 110 °C for 12 h afforded the desired decarboxylated allyl alkynes in good yields.
