Brodzka, Anna,Koszelewski, Dominik,Ostaszewski, Ryszard
, p. 96 - 101 (2012)
The studies on enzymatic kinetic resolution of 3-phenyl-4-pentenoic acid esters were performed. The obtained results demonstrated that the careful choice of biocatalyst and a reaction type are very important for successful enzymatic kinetic resolution. Ki
An unusual β-vinyl effect leading to high efficiency and enantioselectivity of the amidase, nitrile biotransformations for the preparation of enantiopure 3-arylpent-4-enoic acids and amides and their applications in synthesis

(Chemical Equation Presented) Biotransformations of 3-arylpent-4- enenitriles catalyzed by Rhodococcus erythropolis AJ270, a nitrile hydratase/amidase-containing microbial whole-cell catalyst were studied, and an unusual β-vinyl effect of the substrate on
Synthesis of versatile chiral intermediates by enantioselective conjugate addition of alkenyl Grignard reagents to enamides deriving from (R)-(-)- or (S)-(+)-2-aminobutan-1-ol

Conjugate addition of but-3-enylmagnesium bromide to the chiral crotonamide (R)-(+)- and (S)-(-)-3, followed by hydrolysis and oxidation, afforded enantiopure (R)-(+)- and (S)-(-)-3-methyladipic acids 8, respectively. Conjugate addition of vinylmagnesium chloride to the chiral crotonamide and cinnamamides (R)-(+)-3-5, followed by hydrolysis, gave the alkenoic acids (S)-12-14, respectively. Iodolactonization of the latter led to the 5-iodomethyllactones (+)-15-17, which were reduced by means of n- Bu3SnH into the trans-disubstituted 5-methyllactones (+)-19-21, respectively. Treatment of the iodomethyllactone (+)-16 with LiMe2Cu or n- Bu2CuLi furnished the trans-5-alkyl-4-phenyllactones (-)-22 or (+)-23.
