DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) The title compds. I (R = alkyl) is prepd. by asym. alkylation of unsatd. compds.There are some commonly used reagents with their cas registry numbers 5096-11-7 and 127633-95-8 in this article. having CHO group on a pyridine ring by dialkylzinc in the presence of optically active norephedrine derivs. II [R1, R2 = alkyl, (halo- or NO2-substituted) Ph; R1R2 may be bonded to form a group] or III (R1, R2 = same as II). Thus, 3-pyridinecarboxaldehyde was treated with Et2Zn in hexane in the presence of (1S,2R)-(-)-dibutylnorephedrine at room temp. for 1 h to give 99% (-)-1-(3-pyridyl)propanol in 74% enantiomer excess. .
