• Isosteviol-amino Acid Conjugates as Highly Efficient Organocatalysts for the Asymmetric One-pot Three-component Mannich Reactions

  日期：2011.7

  Isosteviol‐amino acid conjugates were synthesized and used as chiral catalysts for the asymmetric three‐component Mannich reaction with hydroxyacetone as donor molecule. Good yields (up to 98%) and excellent stereoselectivities (up to 97:3 dr and 99% ee) were achieved in a short reaction time. In addition, syn‐ or anti‐configurations of α‐hydroxy‐β‐amino carbonyl compounds were obtained as main products

• Simple and inexpensive threonine-based organocatalysts for the highly diastereo- and enantioselective direct large-scale syn-aldol and anti-Mannich reactions of α-hydroxyacetone

  Simple and inexpensive threonine-based organocatalysts that promote syn-aldol reactions and three-component asymmetric anti-Mannich reactions of alpha-hydroxyacetone achieving a respectable level of enantioselectivities are reported. The syn-aldol products could be obtained with up to a 99:1 syn/anti ratio and > 99% ee while the anti-Mannich products could be obtained with up to a 96:4 anti/syn ratio and > 99% ee. Catalyst 1c can be used efficiently on a large-scale with the enantioselectivities of the syn-aldol and anti-Mannich reactions being maintained at the same level, which offers a great possibility for application in industry.
