Abstract

May-Jun 1987 Pyridylethyl: A Versatile Protecting Group. Part II [1]. The Protection of Heterocyclic NH Groups Alan R. Katritzky*, Ghulam R. Khan, and Charles M. Marson Department of Chemistry, University of Florida, Gainesville, FL 32611 USA Received October 6, 1968 Pyrrole, indole, carbazole and imidazole have been protected as iV-[2-(4-pyridyl)ethyl] derivatives. Deprotection occurred under mild conditions after quaternisation. 3- ...
