NHC-catalyzed spiro bis-indane formation via domino stetter - Aldol - Michael and stetter - Aldol - Aldol reactions

Sanchez-Larios, Eduardo,Holmes, Janice M.,Daschner, Crystal L.,Gravel, Michel

, p. 5772 - 5775 (2010)

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.
