β¦ Synopsis
Oxazoline carboxylic acid 6 as the taxol side chain precursor has been efficiently synthesized via the intramolecular iodoamidation ofatlylic trichloroacetimidate derived from trans-olefinic diol l.

A stereoselective synthesis of (4S, 5R)-2,4-diphenyloxazoline-5-carboxylic acid, a precursor of the Taxol C-13 side chain was achieved using palladium-catalyzed oxazoline formation reaction from commercially available amino acid.
Dihydrodihydroxycinnamic acids and their esters react with acetonitrile or benzonitrile in the presence of sulfuric acid to afford the corresponding syn-b-amino-a-hydroxypropionic acid derivatives. High yields and diastereoselectivity of this transformation allows preparation of various phenylisoser
