Zinc/Acid Reduction of 2,3,4,5-Tetraalkylpyrroles
Anderson-McKay, Janet E.,Lawlor, John M.
, p. 1013 - 1024 (2007/10/02)
The stereo- and regio-chemical course of the zinc/acid reduction of C-tetraalkylpyrroles to pyrrolines and pyrrolidines is strongly influenced by experimental conditions, especially the acidity and the nature of the N-substituent
