An attractive feature of this system is its heavily constrained alicyclic backbone that would allow for the exploration of self-assembling systems with conformationally ordered features.

We have developed herein a rhodium-catalysed C-H activation strategy which uses an unprotected anilines and an electron-deficient alkynes to C-C bonded products as a potential intermediate in contrast to the archetypical C-N bonded products with high levels of regioselectivity. This is followed by carbonylation of C-H bond activated intermediate and subsequent annulation into quinolines has been described. This rhodium-catalysed auto-tandem reaction operates under mild, environmentally benign conditions using water as the solvent and CO surrogates as the carbonyl source with the concomitant generation of hydrogen gas. The strategy may facilitate the development of new synthetic protocols for the efficient and sustainable production of chemicals in an atom-economic way from simple, abundant starting materials.</p>1 aMidya, Siba, Prasad1 aSahoo, Manoj, Kumar1 aLandge, Vinod, Gokulkrish1 aRajamohanan, P., R.1 aBalaraman, Ekambaram  uhttps://library.ncl.res.in/content/reversed-reactivity-anilines-alkynes-rhodium-catalysed-c-h-activationcarbonylation-tandem
