An improved procedure for the efficient synthesis of I~-halobutenolides was developed. The Pd(0)catalyzed coupling reactions of 13-halobutenolides with terminal alkynes or organozinc reagents, i.e., 1-alkenyl, aryl, and alkyl zinc reagents, to afford 13-substituted butenolides were carefully studied
