Olefin hydroformylation is a widely used process, both on large scales and in fine chemistry, with catalyst reuse still being one of the main objectives. In recent years, developments in the immobilization of catalysts o...
The chemistry of oligocorannulenes (compounds composed of two or more corannulenyl moieties) arises from the properties of each corannulenyl and from the interactions between them. Varying the linkage between the corannu...
A new family of switches based on a rhodopsin chromophore is presented. These new photoswitches fulfil most of the required features for an efficient switch to be used in practical applications. The synthetic route is si...
A series of mono- to hexachlorinated BODIPY dyes have been prepared in good to excellent yields through the use of N-chlorosuccinimide as an inexpensive halogenating reagent. This library of chlorinated dyes allowed anal...
Efficient hostguest complexation and interesting self-assembled structures formed between two crown ether-based cryptands and a 1,2-bis(4-pyridinium)ethane derivative 3 are reported. By self-assembly of cis-dibenzo-24-cr...
A series of diaryltrisphaeridines have been synthesized by iodination of trisphaeridine and subsequent Suzuki coupling reactions. The photophysical and electrochemical properties of these compounds have been investigated...
()-Isosteviol is a unique ex-chiral-pool building block that is readily available. Both functional groups are aligned in a concave manner. The methyl moiety on the backbone also points in this direction, creating a stron...
Thermal and microwave-assisted [3+2] cycloadditions between differently substituted propiolamidinium tetraphenylborates 3ad and N-methyl-C-phenylnitrone, benzyl azide, and N-(3-azidopropyl)phthalimide were studied. The a...
The synthesis and the characterization of two types of water-soluble beta-cyclodextrin-supported organotin derivatives is described. These new tin-containing macromolecules were prepared through a free radical bishydrost...
For the first time, the beta-anomer of N-acetylglucosamine derivative methyl 2-acetamido-3,4,6-tri-O-benzyl-2-deoxy-beta-D-glucopyranoside (9b) was synthesized, isolated, and used in the synthesis of sugar-based primary ...
A cascade organocatalysis is reported for the nucleophilic and electrophilic dual activation taking place in the reaction of methyl ketones or active methylene compounds with DMF-DMA (N,N-dimethylformamide dimethyl aceta...
The synthesis of 3-aryl-4-nitrocyclohexanones has been achieved from the MoritaBaylisHillman adducts of beta-arylnitroethylenes. The strategy involves proline-catalyzed diastereoselective intramolecular Michael addition ...
We report the tandem Staudinger/aza-Wittig/Ugi three-component reaction mediated synthesis of a 64-member compound library of aza-C-glycosides. The library is composed of four pyrrolidine and three piperidine scaffolds, ...
Herein, a method for the isomerization of the double bonds in tetrahydroxanthones is reported. Tetrahydroxanthones are readily available from salicylaldehydes and cycloalkenones and undergo isomerization upon treatment w...
