This disclosure provides modulators of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) having core structure (I), pharmaceutical compositions containing at least one such modulator, methods of treatment of CFTR mediated diseases, including cystic fibrosis, using such modulators and pharmaceutical compositions, combination pharmaceutical compositions and combination therapies, and processes and intermediates for making such modulators.
Hydroformylation of alkenes can be carried out in a few minutes under microwave activation at a relatively low pressure ( 40 psi) using commercially available catalysts and ligands. The 80 mL vial of a Discover microwave oven was connected to a cylinder of CO and H-2, and after filling the reactor at 40 psi, a mixture of an alkene, the Wilkinson catalyst, and XANTPHOS was submitted to microwave irradiation giving, after 4 min, high conversion into the corresponding aldehyde without formation of the isomerized alkene.

enamides via a ruthenium-catalyzed assisted tandem catalytic ring-closing metathesis–isomerization sequence. The sequence relies on the in situ transformation of a metathesis active Ru–carbene into an isomerization active Ru–hydride by addition of hydroxide as a chemical trigger. N-Allyl-N-homoallylamines were converted in one step into cyclic enamides via a ruthenium-catalyzed assisted tandem catalytic
