A new class of topoisomerase I inhibitors containing the unprecedented benzo[g][1]benzopyrano[4,3-b]indol-6(13H)-one (abbreviated as BBPI) ring system have been developed based on structure-activity relationship studies of the cytotoxic marine alkaloid la

, p. 297 - 308 (2014)
A new total synthesis of terihanine (2a) and isoterihanine (2b) was established by our new bond formation between the C4b and N5 positions of the benzo[c]phenanthridine ring based on a microwave-assisted thermal electrocyclic reaction of 2-cycloalkenylbenzaldoxime as an aza 6π-electron system. In addition, the antitumor activity of these synthesized compounds, including nitidine and nornitidine was evaluated in HCT-116 cells.
Synthesis and evaluation of topoisomerase I inhibitors possessing the 5,13-dihydro-6H-benzo[6,7]indolo[3,2-c]-quinolin-6-one scaffold

, p. 1032 - 1052 (2019/07/31)
Novel topoisomerase I inhibitors possessing the 5,13-dihydro-6H-benzo[6,7]indolo[3,2-c]quinolin-6-one (BIQ) scaffold were designed and synthesized. This scaffold was constructed using sequential and regioselective functionalization of the pyrrole core thr
Thermolytic Synthesis of Naphthalenes via Intramolecular Cyclocondensation of o -Phenylallylbenzaldehydes
Chang, Meng-Yang,Hsueh, Nai-Chen
, p. 3408 - 3419 (2018/06/20)
The development of intramolecular carbonyl-ene type cyclocondensation of oxygenated o -phenylallylbenzaldehydes in refluxing decalin is reported. The facile and easy-to-operate thermolytic rearrangement procedure generates substituted naphthalenes in good to excellent yields.Georg Thieme Verlag Stuttgart - New York.
Efficient One-Pot Synthesis of Tetrahydronaphtho[2,1-f]isoquinolines by Using Domino Pictet–Spengler/Friedel–Crafts-Type Reactions

, p. 6434 - 6440 (2017/12/01)
This study describes a facile and efficient one-pot method for the synthesis of a tetrahydronaphtho[2,1-f]isoquinoline alkaloid. An N-protected amino aldehyde biaryl substrate underwent domino Pictet–Spengler/Friedel–Crafts-type cyclization reactions to p

Iodine-Induced Reaction Cascades for the Rapid Construction of Variously Substituted Benzothiophenes
Hessian, Karl O.,Flynn, Bernard L.
, p. 4377 - 4380 (2007/10/03)
(Equation presented) Readily accessible propynols with a 2-thioxyphenyl substituent selectively undergo 5-exo-iodocyclization followed by tandem rearrangement and elimination or substitution processes to give selective access to either 2-acyl- or 2-(1-iod
12H-[2]-benzothiepino[6,5a,5-bc]benzofuran: Synthesis of a sulfur-analog of galanthamine
Treu, Matthias,Jordis, Ulrich,Mereiter, Kurt
, p. 1727 - 1735 (2007/10/03)
An analog of the anti-Alzheimer drug galanthamine, carrying a SO2-moiety instead of an amino-functionality, has been synthesized as a racemic mixture using tandem cyclization techniques to form a new four membered heterocyclic ring system.
Synthesis and biological activity of some antitumor benzophenanthridinium salts
Stermitz,Gillespie,Amoros,Romero,Stermitz,Larson,Earl,Ogg
, p. 708 - 713 (2007/10/05)
A facile synthesis of benzophenanthridinium salts was developed and used for preparing a number of these compounds. The antitumor activities in mouse leukemia L1210 (LE) and P388 (PS) were determined as well as some selected antimicrobial activities. Alth
