Abstract
A phosphine-free, efficient protocol for aminocarbonylation and carbonylative Suzuki-Miyaura coupling has been developed using a novel palladium complex, [PdII(DMAP)2(OAc)2]. The complex was successfully synthesized using a stoichiometric reaction between PdII(OAc)2 and DMAP in acetone at room temperature and characterized using single-crystal X-ray analysis. Only 5 mol % catalyst loading was sufficient for effective carbonylative transformations. "Chloroform-COware" chemistry was utilized for safe and facile insertion of the carbonyl unit using chloroform as an inexpensive CO source in a two-chamber setup. Various value-added pharmaceutically relevant compounds such as CX-516, CX-546, and farampator were synthesized using the technique. Furthermore, the commercially designed COware was engineered to COware-RB setup for sequential one-pot synthesis of indenoisoquinolines (topoisomerase I inhibitors).

Abstract
An efficient approach for the synthesis of N-substituted indenoisoquinolinones via rhodium(III)-catalyzed C-H bond activation/subsequent [4 + 2] cyclization starting from easily available 2-phenyloxazolines and 2-diazo-1,3-indandiones has been developed. A series of indeno[1,2-c]isoquinolinones were obtained in up to 93% yield through C-H functionalization, followed by intramolecular annulation, elimination, and ring-opening in a "one pot manner" under mild reaction conditions. This protocol features excellent atom- and step-economy and provides a novel strategy for the synthesis of N-substituted indenoisoquinolinones and a chance to study their biological activities.

Abstract
Previously, we have studied the trifluoroacetic acid (TFA)-catalyzed rearrangements of unsubstituted and alkoxy-substituted ortho-(pivaloylaminomethyl)benzaldehydes and revealed the formation of rearranged, regioisomeric aldehydes along with dimer-like products ("TFA dimers"). In the present study, related reactions of ortho-(pivaloylaminomethyl)benzaldehydes are described with the difference that boron trifluoride diethyl etherate (BF3·OEt2) is used as the catalyst. Although in these reactions the formation of the same "TFA dimers" can be observed after a couple of hours reaction time, during further stirring these are transformed into a new dimer-like keto compound ("BF3 dimer") that gradually becomes the main product. Apart from this, an oxoindene-type by-product is also formed. The new products are characterized by detailed NMR studies and two of them also by single-crystal X-ray diffraction. DFT calculations support the mechanism proposed for the transformations and explain the differences observed in the product distribution.

Abstract
The discovery that certain indenoisoquinolines inhibit the religation reaction of DNA in the topoisomerase I-DNA-indenoisoquinoline ternary complex led to a structure-based drug design research program which resulted in three representatives that entered Phase I clinical trials in cancer patients at the National Cancer Institute. This has stimulated a great deal of interest in the design and execution of new synthetic pathways for indenoisoquinoline production. More recently, modulation of the substitution pattern and chemical nature of substituents on the indenoisoquinoline scaffold has resulted in a widening scope of additional biological targets, including RXR, PARP-1, MYC promoter G-quadruplex, topoisomerase II, estrogen receptor, VEGFR-2, HIF-1α, and tyrosyl DNA phosphodiesterases 1 and 2. Furthermore, convincing evidence has been advanced supporting the potential use of indenoisoquinolines for the treatment of diseases other than cancer. The rapidly expanding indenoisoquinoline knowledge base has provided a firm foundation for further advancements in indenoisoquinoline chemistry, pharmacology, and therapeutics.

Abstract
In order to find out the influence of carboxylic acid functionalities in the N-lactam side chains of indenoisoquinolines on cytotoxic activities, several new compounds have been synthesized and structurally characterized by analytical and spectral methods. The incorporation of a carboxylic acid group into the lactam side chain of indenoisoquinolines results in differences in cytotoxicity. The results indicated that compound 18c displayed substantial cytotoxic specificity toward KB and HepG2 cancer cells.

Abstract
This account provides an overview of recent work, including our own contribution dealing with Suzuki–Miyaura cross coupling in combination with metathesis (or vice-versa). Several cyclophanes, polycycles, macrocycles, spirocycles, stilbenes, biaryls, and heterocycles have been synthesized by employing a combination of Suzuki cross-coupling and metathesis. Various popular reactions such as Diels–Alder reaction, Claisen rearrangement, cross-metathesis, and cross-enyne metathesis are used. The synergistic combination of these powerful reactions is found to be useful for the construction of complex targets and fulfill synthetic brevity.

Abstract
The structure-activity relationships and hit-to-lead optimization of dual Top1-TDP1 inhibitors in the indenoisoquinoline drug class were investigated. A series of nitrated 7-, 8-, 9-, and 10-hydroxyindenoisoquinolines were synthesized and evaluated. Several compounds displayed potent dual Top1-TDP1 inhibition. The 9-hydroxy series exhibited potencies and cytotoxicities vs Top1 that surpassed those of camptothecin (CPT), the natural alkaloid that is being used as a standard in the Top1-mediated DNA cleavage assay. One member of this series was a more potent Top1 inhibitor at a concentration of 5 nM and produced a more stable ternary drug-DNA-Top1 cleavage complex than CPT.

Abstract
A rhenium-magnesium cocatalyzed [4+2] annulation of benzamides and alkynes via C-H/N-H functionalization is described. The reaction features a divergent and high level of diastereoselectivities, which are readily switchable by subtle tuning of reaction conditions. Thus, a wide range of both cis- and trans-3,4-dihydroisoquinolinones is expediently synthesized in a highly atom-economical manner. Moreover, mechanistic studies unraveled a tandem mode of action between rhenium and magnesium in the catalytic cycles.

Abstract
Hydroxylated analogues of the anticancer topoisomerase I (Top1) inhibitors indotecan (LMP400) and indimitecan (LMP776) have been prepared because (1) a variety of potent Top1 poisons are known that contain strategically placed hydroxyl groups, which provides a clear rationale for incorporating them in the present case, and (2) the hydroxylated compounds could conceivably serve as synthetic standards for the identification of metabolites. Indeed, incubating LMP400 and LMP776 with human liver microsomes resulted in two major metabolites of each drug, which had HPLC retention times and mass fragmentation patterns identical to those of the synthetic standards. The hydroxylated indotecan and indimitecan metabolites and analogues were tested as Top1 poisons and for antiproliferative activity in a variety of human cancer cell cultures and in general were found to be very potent. Differences in activity resulting from the placement of the hydroxyl group are explained by molecular modeling analyses.
