Synthesis and Application of Novel Proline-Derived Chiral Piperazinones and Sulfamide-Amine Alcohols
摘要:
Several novel chiral piperazinone and sulfamide-amine alcohols were synthesized starting from inexpensive and readily available L-proline and trans-4-hydroxy-L-proline. The catalytic activity of the sulfamide-amine alcohols for the asymmetric addition of diethylzinc to benzaldehyde were evaluated preliminarily.
