Abstract

Rhodium-Catalyzed Addition-Spirocyclization of Arylboronic Esters Containing -Aryl ,-Unsaturated Ester Moiety. -Spirocyclic 1-indanones are synthesized by rhodium-catalyzed spirocyclization involving sequential transmetalation, intramolecular addition to a C=C bond, and -oxygen elimination. A 1,4-rhodium migration is observed. -(MATSUDA*, T.; YASUOKA, S.; WATANUKI, S.; FUKUHARA, K.; Synlett 26 (2015) 9, 1233-1237, http://dx.doi.org/10.1055/s-0034-1378691 ; Dep. Appl. Chem., Fac.
