A new method for the preparation of 2-substituted oxazolines by rhodium-catalyzed coupling of alkenes with 4,4-dimethyl-2-oxazoline is reported. The oxazoline products are obtained in good yield with excellent selectivity for the linear product. A variety of alkene substitution patterns and functional groups are tolerated. This procedure represents an attractive alternative to hydroesterification because
