Vedejs, E. Monahan, S. D. Metalation of oxa-zole—borane complexes a practical solution to the problem of electrocydic ring opening of 2-lithiooxazoles./. Org. Chem. 1996, 61, 5192— 5193. [Pg.220]

Protection of oxazoles. 2-Lithiooxazoles are liable to undergo ring opening thus, alkylation of the heterocycle via the lithiated species is problematic. On the other hand, oxazole-borane complexes behave normally during deprotonation. The borane moiety is easily removed after the alkylation by treatment with HOAc. [Pg.43]
