An efficient, one-pot synthesis of multisubstituted 2-aminoquinolines from 1-aryl tetrazoles and internal alkynes has been developed. The reaction involves cyclization of 1-aryl tetrazoles with internal alkynes via rhodium(III)-catalyzed double C–H activation and copper(II)-mediated denitrogenation.

substituted tetrazole-N-aryl/heteroaryl derivatives is discussed here. The energetic functional groups –NO2, –NHNO2 and –N3 are reliably inserted into the molecular backbone, making the tetrazole-N-aryl derivatives highly energetic and insensitive to heat and impact. For example, the tetrazole derivatives 7 and 8, bearing a –NO2 or a –NHNO2 group, exhibit energetic properties close to RDX, but with enhanced
