The synthesis of diversely functionalized carbohydrate building blocks is of great interest towards the generation of new carbohydrate mimetics. Glycoaminoxy acids are recently developed glycoamino acid analogues with bo...
We hereby describe an instance of diastereoselective trifluoromethanesulfonic acid catalyzed 1,3-dipolar cycloaddition of a trifluoromethylated azomethine imine with alpha,beta-ethenyl ketones. Using two different reacti...
Four linear aromatic disulfonic acids were prepared, which are structurally similar to dicarboxylic acids commonly used as linker molecules for metal-organic frameworks. 4,4'-Biphenyldisulfonic acid was prepared in three...
An easy, two-step approach to various 5-carboxymethyl-2(5H)-furanones is described. A detailed study of the reaction of beta-carboxymethyl enamino esters with N-bromosuccinimide is presented.
Ligand-free palladium-catalyzed Suzuki-Miyaura cross-coupling of iodoethynes with arylboronic acids under aerobic conditions has been developed. In the presence of palladium(II) acetate and cesium carbonate, a variety of...
A series of electronically deficient atropisomeric bisphosphine ligands have been synthesized from (S)-MeO-BiPhep. The introduction of electron-withdrawing groups in the ligands had a dramatic influence on both the enant...
Iron(II) chloride catalyzed direct alkylation of sp(3) C-H bond adjacent to oxygen in propargyl ethers has been accomplished by the use of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as oxidant under mild reaction co...
2-Alkynylbenzaldoxime reacts with phenol under the catalysis of silver triflate in the presence of bromo-tris-pyrrolidinophosphonium hexafluorophosphate (PyBroP) under mild conditions, leading to the formation of 1-aroxy...
