Successive treatment of arenes with β-bromopropionyl chloride and AlCl3, followed by the reactions with hydrazines and Na2CO3, and then with MnO2 gave the corresponding 3-arylpyrazoles in one pot in good to moderate yields. The same successive treatment of arenes with β-bromopropionyl chloride and AlCl3, followed by the reactions with hydroxylamine and KF gave the corresponding 3-arylisoxazolines in one pot in good to moderate yields.

supporting information; experimental part, p. 1243 - 1246 (2011/07/31)
A catalytic enantioselective synthesis of a new class of quinolizidines and indolizidines is presented. An asymmetric Bronsted acid catalyzed hydrogenation cascade as well as a sequential Bronsted acid/metal catalyzed hydrogenation protocol of 2-substituted quinolines yields benzofused quinolizidines and indolizidines in good yields with high diastereo- and enantioselectivities.
