โฆ Synopsis
l-3-(2-propenyl)pyrrole ( 2) and E-and ketoxime ('l) with acetylene in the via the reaction of 3-butenyl methyl OH-DMSO system is reported.
Pyrroles with unsaturated substituents are known to be useful starting species for syntheses of a variety of functionalized pyrrole compounds which now attract an ever-growing attention '*2, preparation are so far quite limited'.
