Several tetrasubstituted NH pyrroles, functionalized with ester or ketone groups at C-3 position, were prepared by one-pot coupling of secondarypropargylicalcohols with 1,3-dicarbonylcompounds and tert-butyl carbamate, via in situ deprotection of the corresponding pentasubstituted N-Boc pyrroles. The three-component coupling process was promoted by the combined use of the 16-electron ruthenium(II)
