  Regio-, stereo-, and enantioselectivity in the electrophilic reactions of 2-amino-4-phenyl-3-butenenitriles

  摘要：

  The allylic anion generated from 2-(N-methylanilino)-4-phenyl-3-butenenitrile (1) reacted with iodomethane and 3-bromo-1-chloropropane in THF/HMPA to give the gamma-substitution products exclusively, predominantly in the 2Z-configuration. Substitution of the N-methylanilino group with the methyl ether of L-(-)-ephedrine resulted in the generation of chiral aminonitrile 2. Lithiated 2 reacted sluggishly in THF with allyl bromide and benzyl chloride in the absence of HMPA to give the gamma-substitution products predominantly in the 2Z-configuration, with little diastereoselectivity. The aminonitrile 3 prepared from cinnamaldehyde, L-(-)-ephedrine, and KCN was lithiated with 2 equiv of LDA resulting in high facial selectivity (76-100% diastereomeric excess) in alkylations in the presence of HMPA and LiI. Lithiated 3 reacted with propionaldehyde, benzaldehyde, and p-bromobenzaldehyde at-78-degrees-C to give the gamma-addition products, predominantly in the 4R-configuration (64-78% de). The stereochemistry of the isomers of each product was determined by chemical correlation and spectral methods including analyses of the CD spectra and X-ray diffraction. A bicyclic transition state C wherein lithium is chelated by both amino and alkoxy groups is proposed to interpret the observed stereoselectivity.

  摘要：

  The electronduction of chiral 3-trans-cinnamoyl-2-oxazolidinones with acid anhydrides gave beta-acylated products stereoselectively. The products were transformed to optically active cis-beta,gamma-disubstituted-gamma-lactones. (C) 1999 Elsevier Science Ltd. All rights reserved.

• Kinetic Resolution and Dynamic Kinetic Resolution of γ‐Aryl‐Substituted Butenolides via Copper‐Catalyzed 1,4‐Hydroboration

  Kinetic resolution (KR) and dynamic kinetic resolution (DKR) of γ‐aryl and heteroaryl‐substituted butenolides via CuH‐catalyzed 1,4‐hydroboration using pinacolborane is reported. With a copper‐Ph‐BPE catalyst, selectivity factors were extremely high (s=>400) with regard to the kinetic resolution of β‐methyl‐γ‐phenyl butenolide; DKR was possible in the presence of an amine base (DBU), which facilitated racemization

  The rhodium-catalyzed 1,2-addition of chiral benzylic secondary alkylboronic esters with a coordinating carbonyl group to aldehydes was demonstrated with high levels of enantiospecificity. Pinacol boronic ester derivatives can be employed directly for the addition in the presence of KHF2 without the use of corresponding trifluoroborate salts where retention of the configuration was observed.
