摘要：

The molybdenum-promoted cycloisomerization of terminal alkynes tethered to nitrogen nucleophiles is described. Reaction of N-carbamoyl alkynylamines with (Et3N)Mo(CO)(5) affords cyclic enecarbamates, Similarly, cyclization of 2-ethynylaniline gives the isomeric indole heterocycle, although N-3-butynylaniline affords the cyclic metal azacarbene product.
