The 1H and 13C NMR chemical shifts of substituted 1,4-dephenyl-2-butene-1,4-diones indicate that these compounds in CDCl3 solution exist mainly in the s-trans-s-trans (Z) keto (trans Z) configuration and that hydrogen bonding between the NH proton an

The rationale for investigating conformationally restricted analogues of BW245C as DP-receptor ligands and the syntheses of three such racemic bicyclic imidazolidinone analogues are described. Compounds 7 (BW587C), 8 (BW480C85), and 9 (BW572C85) were

A new method for measuring and assigning long-range 1 H– 13 C spin coupling constants is presented. This is based on the HSQC pulse sequence with substitution of the 180° 1 H pulse by a selective 180° 1 H pulse and a 180° 13 C pulse in the middl

Aryl substituted 1H-imidazo[1, 2-a]imidazole 8, imidazo[2,1-b]thiazole 9, 1,4-dihydroimidazo[4,5-d]imidazole 11, and 1(2),4-dihydroimidazo[4,5-c]pyrazoles 12–17 have been prepared. An X-ray crystallographic study confirmed the structure of 8 and sh

The pKa, values of six sulmazole analogues were measured spectrophotometrically. The major protonation sites for most of these bridgehead nitrogen heterocycles were determined by 1H and 13C NMR methods. The aryl-substituted imidazo[1,2-a]pyrimidine (
