  (S)-NOBIN-L-prolinamide was employed as organocatalyst in the direct aldol reactions of different ketones and aromatic aldehydes using dioxane as solvent and in the presence of water as additive. Acetone led to the aldol products in up to 93% ee, while cyclic ketones furnished the anti-aldols in moderate to high yield, excellent diastereoselectivity (up to > 99/< 1 anti/syn ratio) and high ee (up to 95%).

  Ficin from fig tree latex displayed a promiscuous activity to catalyze the direct asymmetric aldol reactions of heterocyclic ketones with aromatic aldehydes. Ficin showed good substrate adaptability to different heterocyclic ketones containing nitrogen, oxygen or sulfur. The enantioselectivities up to 81% ee and diastereoselectivities up to 86:14 (anti/syn) were achieved under the optimized reaction conditions. (C) 2013 Elsevier B.V. All rights reserved.

  With heterocyclic ketones or cyclohexanone, the aldol reactions gave products in high yields and with respectable enantioselectivities (87–99% ee) and diastereoselectivities (up to >99:1 anti/syn). The catalyst could be recycled and reused up to seven times resulting in good yields and with good selectivities. This catalyst is also efficient in large-scale reactions with the enantioselectivities remaining
