Abstract: | Two novel domino NHC-catalyzed spirocyclizations are described herein, enabling the rapid construction of three new carbon-carbon bonds and a quaternary center with high diastereoselectivity. A variety of spiro bis-indane structures are assembled in a single step from simple o-phthaldialdehyde derivatives. |
