Preparation of conjugated soybean oil and other natural oils and fatty acids by homogeneous transition metal catalysis

Journal of the American Oil Chemists Society (2001)

Richard C. Larock Xiaoyang Dong Steven Chung Ch. Kishan Reddy Laurie E. Ehlers

Abstract The use of as little as 0.1 mol% [RhCl(C 8 H 14 ) 2 ] 2 , 0.25 mol% PtCl 2 (PPh 3 ) 2 , or 0.5 mol% RuHCl(CO)(PPh 3 ) 3 , where Ph = phenyl, catalyzes the isomerization of soybean oil to conjugated soybean oil under mild reaction conditions and in high yields. No hydrogenation products are detected with any of these catalysts. Preliminary physical tests have shown that the conjugated soybean oil has exceptional drying properties and the resulting coatings exhibit good solvent resistance. The [RhCl(C 8 H 14 ) 2 ] 2 catalyst provides similarly high yields of other conjugated vegetable oils, conjugated linoleic acid, and conjugated ethyl linoleate. Other rhodium catalysts, such as RhCl(PPh 3 ) 3 , have also been found to be effective for the conjugation of ethyl linoleate.

Convenient Methods for the Synthesis of Chiral 2-Phenylpyrrolidines

Synthetic Communications (1995)

Ch. Kishan Reddy Hariappan Periasamy

Abstract Chiral N-α-methylbenzyl-2-phenylpyrrolidine has been prepared by the reaction of 1-phenyl-1,4-dibromobutane with S-(−)-α- methylbenzylamine. It has been also prepared by the condensation of methyl β-benzoylpropionate with S-(−)-α-methyl benzylamine followed by reduction using NaBH4/I2 and dil. HCl treatment. The diastereomers have been readily separated by chromatography on silica gel column. The lactam obtained by the condensation of S-valinol with β-benzoylpropionic acid on reduction using NaBH4/I2 in THF at −78°C for 6h and then rt for 6h gives (−)-N- [2-(1-hydroxy- 2(R)-isopropylethyl]- 5(S)-phenyl-2-pyrrolidine, [α]25 D = −35.8°C (C 1.5, CH2Cl2) diastereomer (92% d.e) as a major product.
