Abstract
The efficient syntheses of 6,6,8,6,6-pentacyclic naphtho-fused
oxazocinoquinolinones and 6,6,8,6,6,6-hexacyclic benzo[g ]quinoxalino-fused oxazocinoquinolinones
were achieved in one-pot sequences. The generation of libraries
of their diaryl- and alkynyl-substituted analogues via Suzuki-Miyaura
and Sonogashira cross-coupling reactions, respectively, were also
achieved.
Key words
fused-ring systems - oxazocinoquinolinones - diarylations - alkynylations - cross-coupling

20 For the single-crystal X-ray crystallographic
analysis of compound 3a (C21 H15 NO2 ),
yellowish needle-shaped crystals were grown from CHCl3 -MeCN
(7:3); monoclinic, space group P 2(1)/n ; unit cell parameters: a = 14.102(5), b = 15.073(5), c = 15.994(6).
Diffraction data were measured with MoKα (0.71073 Å)
radiation at 296 K using a Kappa Apex 2 instrument. The structure
was solved by direct methods using the SHELX-97 program. Refinements of F
² were carried out
against all reflections using SHELX-97.
