3-Aryl-l-iodoisoquinoline synthesis is developed using titanium tetraiodide induced cyclization of cyanoketones. The method is applied to the short step formal synthesis of CWJ-a-5 having a topoisomerase I inhibitory activity. 3-Iodo-1-phenylisoquinoline synthesis is also reported under the similar reaction conditions.

amines in the presence of Me3Al. The reaction proceeds via a domino nucleophilic addition with subsequent intramolecular cyclisation. This method provides a wide variety of substituted 1-aminoisoquinolines with good functional group tolerance. Furthermore, the synthetic utility of this protocol was demonstrated in the successful synthesis of the antitumor agent CWJ-a-5 in gram scale.

The present invention is directed to novel dihydropyrimidin-2(1H)-one compounds useful as S-nitrosoglutathione reductase (GSNOR) inhibitors, pharmaceutical compositions comprising such compounds, and methods of making and using the same.
Biphenylmethyl-substituted pyridones are prepared by reaction of pyridones with appropriate biphenylmethyl compounds. The biphenylmethyl-substituted pyridones can be employed as active compounds in medicaments, in particular for the treatment of arterial hypertension and atherosclerosis.
sequential nucleophilic addition followed by an intramolecular cyclization of functionalized nitriles with arylboronic acids has been achieved, providing an efficient synthetic pathway to access structurally diverse isoquinolines and isoquinolones. This methodology has also been successfully applied to the total synthesis of the topoisomerase I inhibitor CWJ-a-5 (free base).
