Abstract
AbstractThe asymmetric synthesis of the novel pyranonaphthoquinones ventilanone A and ventilanone B, isolated from the Thai endemic plant Ventilago harmandiana, is accomplished by employing l-rhamnose and gallic acid as the starting materials. The key reactions are the utilization of a newly introduced reagent, PhSCF2H/SnCl4, for the formylation of sterically hindered aromatics containing an electron-withdrawing methyl ester, and the efficient Hauser annulation of phenylthiophthalides with optically active C-1 glycals derived from l-rhamnose. The developed synthetic methodologies solve the long-standing problem of the formylation of sterically hindered aromatics containing electron-withdrawing groups, and are applicable for the synthesis of other analogues with substituents on the aromatic and pyran rings.

Abstract
The first stereoselective total synthesis of the dimeric naphthoquinonopyrano-γ-lactone (-)-crisamicin A was realized (13 steps, 5% overall yield). 1,4,5-Trimethoxynaphthalene, reached in five known steps, was brominated at C-3 to install a but-3-enoic ester by an ensuing Heck coupling. An asymmetric Sharpless dihydroxylation followed and gave a β-hydroxy-γ-lactone with >99.9% ee. Its OH substituent and acetaldehyde established the dihydropyran ring in a completely diastereoselective oxa-Pictet-Spengler cyclization. The 2,3-fused anisole moiety allowed the C5-H bond under Hartwig's conditions to be borylated. This set the stage for engaging the resulting C5-B bond in an oxidative dimerization, which led to a binaphthohydroquinon-5-yl. The latter was advanced to synthetic crisamicin A by a double CAN oxidation (→ a binaphthoquinon-5-yl) and a double demethylation.

Abstract
Allylic oxidation of 2-allylbenzoic acids to phthalides, instead of Wacker-type isocoumarins, was achieved with 1,2-bis(phenylsulfinyl)ethane palladium(ii) acetate (White catalyst) and oxygen in DMSO. The selective formation of 3-ethylidenephthalides or 3-vinylphthalides was controlled by the addition of acids or bases, and the reaction conditions were applied to substituted 2-allylbenzoic acids to generate corresponding phthalides selectively. Mechanistic studies, including the corresponding reaction of (E)-2-(1-propenyl)benzoic acid to 3-methylisocoumarin, isomerization reaction of 3-vinylphthalide to 3-ethylidenephthalide, and the kinetic isotope effect using 2-(1,1-d2-allyl)benzoic acid, revealed the competition between Wacker-type oxidation and allylic C-H cleavage, which is the key step to generating phthalides. A natural product, 3-ethyl-6-hydroxyphthalide, was prepared by this method.

Abstract
In 1991, WHO recognized the resurgence of tuberculosis as a global health problem. Although modern chemotherapy is effective against the causative pathogen Mycobacterium tuberculosis, the current drug regimens have failed to eradicate the disease. The success of the pathogen, partially attributed to drug resistance, necessitates the development of novel anti-tuberculosis drugs. Benzo[j]phenanthridine-7,12-diones, tetracyclic derivatives of the natural product benz[g]isoquinoline-5,10-dione, were conveniently synthesized via palladium-catalyzed intramolecular cyclization of N-methanesulfonyl-3-bromo-2-(arylamino)methyl-1,4-naphthoquinones. Here we report on the bioactivity of eight benzo[j]phenanthridine-7,12-dione derivatives as candidate drug molecules against M. tuberculosis and on their cytotoxicity on C3A human hepatocytes. The strongest antimicrobial activity (as detected by growth inhibition of bacteria, using luminometry and BACTEC 460-TB) and lowest cytotoxicity was found for 3-methylbenzo[j]phenanthridine-7,12-dione 5e, which was also effective in targeting intracellular M. tuberculosis (in murine J774 macrophages) and was not genotoxic for C3A hepatocytes.

Abstract
The polyketide antibiotic frenolicin B harbors a biosynthetically intriguing benzoisochromanequinone core, and has been shown to exhibit promising antiparasitic activity against Eimeria tenella. To facilitate further exploration of its chemistry and biology, we constructed a biosynthetic route to frenolicin B in the heterologous host Streptomyces coelicolor CH999, despite the absence of key enzymes in the identified frenolicin gene cluster. Together with our understanding of the underlying polyketide biosynthetic pathway, this heterologous production system was exploited to produce analogs modified at the C15 position. Both the natural product and these analogs inhibited the growth of Toxoplasma gondii in a manner that reveals sensitivity to the length of the C15 substituent. The ability to construct a functional biosynthetic pathway, despite a lack of genetic information, illustrates the feasibility of a modular approach to engineering medicinally relevant polyketide products.

Abstract
A variety of iodo-substituted isochromenes, dihydroisobenzofurans, and pyranopyridines are readily prepared in good to excellent yields under mild conditions by the iodocyclization of readily available 2-(1-alkynyl)benzylic alcohols or 2-(1-alkynyl)-3-(hydroxymethyl)pyridines. Reactions are carried out in MeCN at 25 degrees C with 3 equiv of I(2) as the iodine source and NaHCO(3) (3 equiv) as the base. The regiochemical outcome of the reaction strongly depends on the substitution pattern of the starting material. In particular, the 5-exo-dig cyclization mode, leading to dihydroisobenzofurans, is observed in the case of substrates bearing a tertiary alcoholic group, owing to the gem-dialkyl effect, while the 6-endo-dig cyclization mode, leading to isochromene or pyranopyridines, is the usually preferred pathway in the case of substrates bearing a primary or secondary alcoholic group.

Abstract
The naturally occurring pyranonaphthoquinone (PNQ) antibiotic lactoquinomycin and related aglycones were found to be selective inhibitors of the serine-threonine kinase AKT. A set of synthetic PNQs were prepared and a minimum active feature set and preliminary SAR were determined. PNQ lactones inhibit the proliferation of human tumor cell lines containing constitutively activated AKT and show expected effects on cellular biomarkers. Biochemical data are presented supporting a proposed bioreductive alkylation mechanism of action.
