Ultrasound-Mediated One-Pot Synthesis of the Fully Functionalized N,Nʹ-(1,3-Propane)bispyrroles

Abstract

Contents General information Experimental procedures of the strategy NMR spectra General Information Melting points were recorded on a Yanaco hot-stage melting point apparatus and uncorrected. Purification of reaction products was carried out by flash chromatography using EM Reagent silica gel 60 (230-400 mesh). Analytical thin layer chromatography was performed on EM Reagent 0.25 mm silica gel 60-F plates. 1 H NMR spectra were recorded at 400 MHz and 13 C NMR spectra were recorded at 100
