Methyl 1-cyclopentene-1-carboxylate may be used as starting material in the synthesis of pinnaic acid and halichlorine.It undergoes asymmetric oxidative Heck reaction with aryl boronic acids to form coupling products in the presence of chiral NHC (N-heterocyclic carbine)-palladium (II) complex Product Description： Methyl 1-cyclopentene-1-carboxylate, a cyclic alkene, is a cyclopentene derivative. It participates in the synthesis of azulene derivatives by initially forming the corresponding cyclopropanol followed by oxy-Cope rearrangement.
