  Organocatalyzed Baylis–Hillman reaction: an enantioselective approach

  摘要：

  A convenient protocol has been developed for the synthesis of Baylis-Hillman adducts in the presence of a base and an organocatalyst. We have designed and synthesized organocatalysts based on hydrogen bonding using a pyrrolidine ring as the backbone and applied them to Baylis-Hillman transformations. This method provides products in good to high yields (73-90%) and with excellent enantiomeric excesses (up to 96%) and reasonable reaction times. (C) 2012 Elsevier Ltd. All rights reserved.

  An efficient route for the allylation of arylaldehydes to give enantiopure homoallylic alcohols

  摘要：

  An efficient asymmetric synthesis of homoallylic alcohols is described by the allylation of carbonyl compounds using organocatalysts as chiral directors in the presence of tin metal. The effect of chiral environment is also studied on the allylation reactions. This method allows us to obtain two different enantiomers of homoallylic alcohol in the presence of the corresponding chiral compound. The protocol is applied to various aldehydes to obtain high yields and excellent enantioselectivities for the corresponding homoallylic alcohols. (C) 2013 Elsevier Ltd. All rights reserved.
