Preparation of a 3-phenyl-4(3H)-isoquinolinone and its transformation in 12(11H)-Benzo[c]phenanthridinone derivatives. Crystal structure determinations.
摘要:
Trans- and cis-5-(p-toluenesulfonyl)-5,6,13,14-tetrahydro-12(11H)-benzo[c]phenanthridinones have been prepared with excellent yield involving the initial formation of 3-phenyl-2-(p-toluenesulfonyl)-1,2-dihydro-4(3H)-isoquinolinone, as the key intermediate. Spectroscopic studies of the 4(3H)-isoquinolinone and 12(11H)-benzo[c]phenanthridinone derivatives have been developed and their relative configurations have been fully established and confirmed unambiguously by X-ray diffraction analyses.
