SNAr-Based Cycloetherification Methodology: Application in the Synthesis of Heterodectic Macrocyclic Peptides with Endo Aryl-Aryl and Aryl-Alkyl Ether

The endo aryl-aryl and aryl-alkyl ether bonds exist in a number of biologically important macrocyclic natural products, such as vancomycin family glycopeptide antibiotics ( 1 – 3 ), antitumor series RA I-XIV ( 4 ), K-13 ( 5 ), OF4949

Enantioseparations of Primary Amino Compounds by High-Performance Liquid Chromatography Using Chiral Crown Ether-Based Chiral Stationary Phase

Liquid chromatographic resolution of racemic compounds containing a primary amino group has been known to be most successful when chiral crown ether-based chiral stationary phases (CSPs) are used. Among various crown ether

Quantitation of Homovanillic Acid (HVA) and Vanillylmandelic Acid (VMA) in Urine Using Gas Chromatography-Mass Spectrometry (GC/MS)

(VMA). In the following procedure, urine samples are diluted to give a creatinine concentration of 2 mg/dL. Deuterated internal standards are added to the diluted urine samples followed by acidification using HCl. Ethyl acetate is used to extract HVA
