• Chiral 3-aminopyrrolidines as a rigid diamino scaffold for organocatalysis and organometallic chemistry

  Over 20 new and easily prepared diamines were screened for the asymmetric Morita-Baylis-Hillman reaction. Chiral non-racemic 3-(N,N-dimethylamino)-1-methylpyrrolidine was found to promote efficiently the reaction of methyl vinyl ketone and substituted benzaldehydes. Enantiomeric excesses up to 73% were reached with electron-deficient benzaldehyde derivatives. After a simple deprotonation, one of these diamines was transformed into a chiral mixed aggregate for the enantioselective synthesis of (R)-1-o-tolylethanol with 76% ee. (C) 2010 Elsevier Ltd.

  Enantiomerically pure (2S,6S)-2,6-diphenyltetrahydro-2H-thiopyran, (2S)-2-phenyltetrahydro thiophene, and (2S)-2-phenyltetrahydro-2H-thiopyran were prepared in 70-72% yields and with 86-99% ee via cyclization of the corresponding dimesylate in an S(N)2 cyclization reaction using sodium sulfide nonahydrate. The results on the application of various chiral sulfides in asymmetric Baylis-Hillman reactions are also described. (C) 2013 Elsevier Ltd. All rights reserved.

• Chiral thiourea derivatives as organocatalyts in the enantioselective Morita-Baylis-Hillman reactions

  Novel chiral bifunctional thiourea derivatives have been synthesised and successfully applied to the intermolecular Morita-Baylis-Hillman (MBH) reaction of an aromatic aldehyde with methyl vinyl ketone (MVK) and to the intramolecular MBH reaction of omega-formyl-enone. The corresponding products were obtained with high enantioselectivities (up to 98 % ee). The thiourea organocatalyst derived from a B-amino alcohol gave high enantioselectivities (92 % ee) in the intermolecular MBH reaction, whereas the same chiral ligand afforded the corresponding product in high yield (85 %) with moderate enantioselectivity (75 % ee) in the intramolecular MBH reaction. The use of a thiophene ring-containing thiourea derivative gave high enantioselectivities in the intermolecular and intramolecular MBH reactions (85 % and 95 % ee, respectively).[GRAPHICS].
