Disclosed are an amphipathic compound having a penta-saccharide hydrophilic group, a method of preparing the same, and a method of extracting, solubilizing, stabilizing, crystallizing or analyzing membrane proteins and membrane protein complexes using the same. In particular, since the compound has a high-density penta-saccharide hydrophilic group composed of five glucose units, the compound may have an excellent effect on crystallization of membrane proteins. In addition, since the hydrophilic group used in the amphipathic compound has a novel structure, the hydrophilic group may be applied to the development of various amphipathic molecules.

We report the oxyalkynylation of thiiranes and thietanes using ethynylbenziodoxolonereagents (EBXs) to readily access functionalized building blocks bearing an alkynyl, a benzoate, and an iodide group. The reaction proceeds with high atom efficiency most likely through an alkynyl-episulfonium intermediate. The transformation is copper-catalyzed and compatible with a large array of thiiranes and thietanes

achieving the decyanation of disubstituted malononitrilederivatives without using reducing agents has been developed. Treatment of a six-membered malononitrilederivative with NaHMDS followed by methanol afforded the corresponding acetonitrile derivative in high yield. The present method was applicable to the decyanation reactions of a variety of malononitriles including four- and five-membered compounds
An improved synthesis of 4,4-bis(hydroxymethyl)-1,2-diselenolane and the complexation properties of the corresponding diselenolato dianion to group-10 metals are reported. We describe an efficient and straightforward procedure that bypasses the isolation of the malodorous and air-sensitive diselenol and starts with the diselenide and an appropriate group-10 metalcomplexbearingphosphane and chlorido
