Reversed-phase high-performance liquid chromatography (RP-HPLC) is the most popular
chromatographic mode, accounting for more than 90% of all separations. HPLC itself owes …

Stationary phases are the basis of the development and application of high-performance
liquid chromatography (HPLC). In this review we focused on the development of silica …

Amino acids are essential for life, and have many functions in metabolism. One particularly
important function is to serve as the building blocks of peptides and proteins, giving rise to …

Amino acids are very important organic compounds in nature. The biological activity of
amino acids depends mainly on their stereoisomeric configuration (d‐or l‐). Thus, the …

The addition of lithium carbenoids to isocyanates provides a versatile access to N-
substituted 2-haloacetamides: the reaction tolerates the presence of variously functionalized …

The enantiomeric differentiation ability of chiral sugar-based crown ethers can be utilized for
the determination of the enantiomeric composition of chiral amino compounds and for the …

Four novel chiral 22-crown-6 ethers 6a–b, 7a–b bearing hydroxyl side groups derived from
rosin acid and BINOL were prepared in optically pure forms, and their enantiodiscriminating …

Chiral macrocycles with the hydrogen bond donor/acceptor sites in the cavity were
synthesized and covalently bonded to silica gel to give chiral stationary phases (CSPs) …

Starting from commercially available and relatively cheap chemicals first enantiopure
dimethyl-substituted monoaza-18-crown-6 ether (R, R)-21 containing a diphenylamine unit …
