Indolizine studies. Part 2. Synthesis and NMR spectroscopic analysis of 2-substituted indolizines
Abstract
Thermal cyclisation of 3-acetoxy-3-(2-pyridyl)-2-methylenepropionate esters and related compounds provides convenient access to 2-substituted indolizines. Detailed one- and two-dimensional NMR spectroscopic analysis of the title compounds has facilitated interpretation of their 1H and 13C NMR spectra.
