Lehmann, Johannes published the artcileThe Kondrat’eva Reaction in Flow: Direct Access to Annulated Pyridines, Recommanded Product: 5-(4-Bromophenyl)oxazole, the publication is Organic Letters (2013), 15(14), 3550-3553, database is CAplus and MEDLINE.
A continuous flow inverse-electron-demand Kondrat’eva reaction has been developed that provides direct access to cycloalka[c]pyridines from unactivated oxazoles and cycloalkenes. The cycloadditions of both unactivated alkenes and deactivated oxazoles are promoted in continuous flow at elevated temperatures and pressures (230 °C, 750psi). E.g., reaction of 5-phenyloxazole and cyclopentene in presence of TFA gave 55% 4-phenyl-6,7-dihydro-5H-cyclopenta[c]pyridine (I). Annulated pyridines obtained by this one-step process are valuable scaffolds for medicinal chem.
