B(C6F5)3 catalyzed cyclopropanation of 3-alkenyl-oxindoles with diazomethanes to form 25 spirocyclopropane-oxindole derivatives in good to excellent yields (up to 99%) and high diastereoselectivities (up to 20 : 1 d.r.) under mild reaction conditions

Chemoselective insertions of diazoalkanes into 2-hydroxybenzothiazoles are achieved using B(C6F5)3, Rh2(OAc)4 or TfOH as a catalyst, illustrating the complementary nature of Lewis acid, transition metal and Brønsted acid catalyses.
