The preparation of new enantiopure imidazolinium salts and their evaluation as catalysts and shift reagents
摘要:
A series of new chiral imidazolinium salts were prepared and tested as catalysts. It was possible to show that bis-imidazolinium salts had a higher reactivity than mono-imidazolium salts. In addition a chiral discrimination of the bis-imidazolinium salts with the potassium salt of racemic Mosher's acid wits proven by NMR studies. (c) 2006 Elsevier Ltd. All rights reserved.
