초록
Sequential copper-catalyzed [3+2] cycloaddition, rhodium-catalyzed O-H insertion, intramolecular 1,8-addition, and rearrangement starting from 1-alkynes, N-sulfonyl azides, and tropolones is demonstrated for the synthesis of the 2-functionalized aminotropones in one pot. These results indicate that sequential functionalization of O-H and C(sp(2))-O bonds smoothly occurs in the C(sp(2))O-H bonds of tropolone
