The synthesis of two previously unknown unsubstituted heterocyclic ring systems namely, benzo[h][1]benzothieno[2,3-c]quinoline (6) and benzo[f][1]benzothieno[2,3-c]quinoline (12) is reported. TheseExpand
Oxidative photocyclization of N6-benzoyladenosine derivatives. Facile formation of the quinazolinopurine ring system
Irradiation of 2′,3′,5′-tri-O-acetyl-N6-benzoyl adenosine derivatives 1 in the presence of an oxidant resulted in a novel type of the oxidative photocyclization leading toExpand
Synthesis of [1]benzothienonaphthyridines
3-Chlorobenzo[b]thiophene-2-carbonyl chloride reacted readily with 2-amino-, 3-amino-, or 4-aminopyridine to give the corresponding amides. Photocyclization of the amides afforded the followingExpand
The synthesis of [1]benzothieno[2,3‐c]quinolines, [1]benzothieno[2,3‐c][1,2,4]triazolo[4,3‐a]quinoline, and [1]benzothieno[2,3‐c]tetrazolo[1,5‐a]quinoline
Photocyclization of 3-chloro-N-phenylbenzo[b]thiophene-2-carboxamide 10 afforded [1]benzothieno[2,3-c]-quinolin-6(5H)-one 11 which was chlorinated to 6-chloro[1]benzothieno[2,3-c]quinoline 12Expand
Triggered Release of Acids, Bases, Radicals, Nitrenes, and Carbenes
In this chapter the thermal, photochemical, and electrochemical release of acids, bases, and radicals will be surveyed. The reactions which have been most frequently cited in the literature as theExpand
The synthesis of dimethoxy[1]benzothieno[2,3-c]quinolines
A series of dimethoxy[1]benzothieno[2,3-c]quinolines have been prepared by photocyclization of the appropriate N-phenyl-3-chlorobenzo[b]thiophene-2-carboxamides. The lactams obtained were convertedExpand
