A facile protocol for the unprecedented one-pot H 2 SO 4 -mediated hydroxymethylation/cyclative N, O -acetalization of 4-aminocoumarins to 1,4-dihydro-2 H,5 H -chromeno[4,3- d ][1,3]oxazin-5-ones, in moderate to good yields, was deve
Transition-metal free C(sp2)-C(sp2) bond formation: Arylation of 4-aminocoumarins using arynes as an aryl source

A mild, efficient and transition-metal free synthetic strategy has been developed for the α-arylation of 4-aminocoumarins. This synthetic strategy proceeds via C(sp2)-C(sp2) bond formation between 4-aminocoumarins and aryne precursors in a single step by simple treatment with a fluoride source in the absence of a metal-catalyst. Moreover, this methodology affords good yields of 4-amino-3-arylcoumarin derivatives bearing halide functionality.

Pyrroles, ubiquitous bioactive heterocycles in nature, are readily prepared via a palladium-catalyzed oxidative annulation of cyclic trans-enamines to various internal alkynes in the absence of a directing group. Copyright
