A Rh-catalyzed ortho-amidation cyclocondensation sequence gave a range of 4-aminoquinazolines in high yield. The method features a remarkably mild C(sp2)-H activation step and can be exploited to rapidly access compounds with established biological activity.

A catalytic protocol for the base-mediated amidation of unactivated esters with amino alcohol derivatives is reported. Investigations into mechanistic aspects of the process indicate that the reaction involves an initial transesterification, followed by an intramolecular rearrangement. The reaction is highly general in nature and can be extended to include the synthesis of oxazolidinone systems through use of dimethyl carbonate.

(Chemical Equation Presented) A catalytic amidation of unactivated esters with amino alcohols is described. A series of solution studies in addition to the first X-ray structure of a carbene-alcohol complex support a carbene-base nucleophile activation mechanism.
