Synthesis of 5-phenyl 2-functionalized pyrroles by amino Heck and tandem amino Heck carbonylation reactions

2-Methyl-, 2-(methoxycarbonyl) methyl-, and 2,2-[(ethoxycarbonyl)(methoxycarbonyl)] methyl-5-phenylpyrroles are prepared from the corresponding 3-butynyl and 4-(methoxycarbonyl)-3-butynyl phenyl ketone O-pentafluorobenzoyl oximes by amino Heck cyclization and tandem amino Heck carbonylation, respectively.
