2-Phenylquinazolin-4(3H)-one, a class of potent PDE5 inhibitors with high selectivity versus PDE6
摘要:
In our efforts to minimize the side effects associated with low selectivity against the other PDE isozymes, a novel class of 2-phenylquinazolin-4(3H)-one derivatives were designed and prepared as potent PDE5 inhibitors with high selectivity against PDE6. The syntheses and SAR studies of such molecules were reported. (C) 2009 Elsevier Ltd. All rights reserved.

The rhodium catalyzed annulation of anilines with alkynic esters allowing for the high-yieldsynthesis of quinoline carboxylates with excellent regioselectivity is described. This unprecedented reaction employs either formic acid as the C1 source and reductant or copper(II) as the oxidant and is proposed to proceed via rhodacycle of in situ generated amide and enamine ester followed by ortho C–H activation
