    • Compound 12 is presumably derived from the attack of the oxazolidone carbonyl by peroxide, reduction by sufite to the acyl carbamic acid, and decarboxylation.

    • Using either DCC or BOP as coupling reagents, amide formation required 3-4 days and resulted in product yields of 44% and 36%, respectively.
