  日期：——

  Addition reaction of 3,4-dihydroisoquinolines with γ-hydroxy-α,β-unsaturated ketones furnished a variety of diastereomerically pure oxazolo[2,3-a]tetrahydro-isoquinolines, which could be purified by either recrystallization or solvent evaporation. The reaction proceeded smoothly under “green” conditions without an additive and catalyst, giving the target molecules in good to excellent yields.

  synthesis of furan-embedded styrene atropisomers via the reaction between 1-(aryl-ethynyl)-naphthalen-2-ol and γ-hydroxyenone. The reaction proceeds through in situ furan formation from γ-hydroxyenone. The styrene derivatives were obtained in moderate to good yields with high diastereoselectivities with a catalytic amount of PTSA. Few applications such as triazole formation and cross-coupling reactions

• Enantioselective, Organocatalytic Oxy-Michael Addition to γ/δ-Hydroxy-α,β-enones:  Boronate-Amine Complexes as Chiral Hydroxide Synthons
  作者：De Run Li、Andiappan Murugan、J. R. Falck

  DOI：10.1021/ja076802c

  日期：2008.1.1

  An organocatalytic, enantioselective oxy-Michael addition to achiral gamma- and delta-hydroxy-alpha, beta-enones was developed. The key transformation is an unprecedented, asymmetric conjugate addition triggered by complexation between an in situ generated boronic acid hemiester and a chiral amine catalyst. Functionally, the intermediate amine-boronate complex acts as a chiral hydroxide surrogate or synthon. The resultant chiral beta-hydroxy-ketones are obtained in good to excellent yields and high ee following mild oxidative removal of the cyclic boronate. Natural products (R,12Z,15Z)-2-hydroxy-4-oxohenicosa-12,15-dienyl acetate and (+)-(S)-streptenol A were synthesized to demonstrate the utility of this reaction.

  A convenient synthesis of 2,5-disubstituted furan was developed by employing donor–acceptor oxiranes in a new reaction with γ-hydroxyenones. Sc(OTf)3 was found to be the best catalyst, and 2,5-disubstituted furans are obtained in moderate to good yields under mild reaction conditions. The scope of the reaction is quite decent, allowing for the synthesis of disubstituted furans having aryl and heteroaromatic
