Diazo compounds and diazirines have been separately studied in detail and are widely used in research and for applied purposes. Although the mutual isomerization of these compounds was discovered 50 years ago, it has sti...
Benzimidazoles may be formed in high yield through the phosphite-triggered reductive cyclization of o-nitroaniline derivatives. This reaction was used for the one-pot synthesis of benzimidazoles from o-nitrophenols and i...
In this work peracetylated lactose and related compounds have been tested as advanced intermediate substrates in enzymatic deprotections catalyzed by acetyl xylan esterase (AXE) from Bacillus pumilus. In particular, we p...
Three suitably oriented squaramido ammonium groups form the basis of the first abiotic receptor that employs the noncovalent ammonium-carboxylate electrostatic interaction and a hydrogen bond to achieve high-affinity mol...
A new class of tribranched dye-sensitized solar cell (DSC) sensitizers carrying two conjugated donors and two acceptor/anchoring groups is introduced. The approach leads to significantly different optical properties and ...
We describe the synthesis and photophysical properties of 11 substituted 5-(benzothiazol-2-yl)-2'-deoxyuridine derivatives and oligodeoxyribonucleotides (ODNs) containing 5-(5,6-dimethoxybenzothiazol-2-yl)-2'-deoxyuridin...
Preparation of piperidine-2-one scaffolds by the hetero-Diels-Alder (HAD) reaction, assisted by microwaves, is described. The versatility of this new approach has been demonstrated by the synthesis of racemic (+/-)-2-phe...
The electronic properties of bis[2-(2-hydroxyphenyl)benzothiazolato]zinc(II) complexes were tuned by attachment of electron-withdrawing and -donating aryl groups through the Suzuki-Miyaura coupling reaction. Optimization...
A (2+1) glycosylation approach was employed to construct the core structure of a trisaccharide found in the soil bacterium Geobacillus stearothermophilus. The phospholipid was assembled by the reaction of a peracetylated...
Copper-catalyzed arylation of oxadiamines and polyamines aimed at the synthesis of N,N'-diaryl derivatives using bromo- and iodoarenes was studied. Conversion of the starting compounds, selectivity of the arylation of pr...
Experimental and computational evidence suggests that the cleavage of n-butyl and tert-butyl 3-bromodiazirine-3-carboxylates by sodium n-butoxide in DMF, affording high yields of dibutyl carbonates, may proceed by nucleo...
The oxidative carbonylation of aniline to N,N'-diphenylurea was carried out by using W(CO)(6) as the catalyst, I(2) as the oxidant, CO as the carbonyl source and 4-(dimethylamino)pyridine (DMAP) as base. The reaction con...
Thiocarbonyl S-oxides (sulfines) derived from aliphatic and cycloaliphatic thioketones were irradiated in argon matrices at 10 K, and the resulting oxathiiranes were identified by comparison of computed and experimental ...
Rice blast fungus, Magnaporthe grisea, produces a series of salicylaldehyde-type phytotoxins such as pyriculol, pyricuol, and pyriculariol. Plausible biosynthetic intermediates of these phytotoxins were synthesized in de...
We describe a synthetic strategy for the angelimicin family of anthraquinoid natural products that involves converting a central highly oxygenated decalin intermediate to the AB and A'B' subunits. Herein, we report the s...
Chiral allylic benzotriazole-containing regioisomers 4 and 5 were synthesized by enantioselective palladium-catalyzed allylation of sodium benzotriazolide with a range of allylic carbonates in 50-89% yields, regioselecti...
