Bis(catechol) ligands derived from 2,8-disubstituted analogues of Troger's base and monofunctionalized MOM-protected or unprotected catechols bearing both rigid and flexible spacers were synthesized, which gave rise to dissymmetric oxygen donor ligands whose geometry is defined by the V-shaped and rigid structure of the core of Troger's base. These racemic ligands undergo self-assembly to dinuclear
The present invention relates to a condensed heterocyclic compound that has an enteropeptidase inhibitory effect and is useful in the treatment or prevention of obesity, diabetes mellitus, or the like, and a medicament containing the same. Specifically, the present invention relates to a compound represented by the following formula (I) or a salt thereof, and a medicament containing the same [in the formula, each symbol is as defined in the specification].
Twonaturallyoccurring 3-methyl-2,5-dihydro-1-benzoxepin carboxylic acids, 6-hydroxy-3-methyl-8-(phenylethyl)-2,5-dihydro-1-benzoxepin-9-carboxylic acid (radulanin E) (1) and 9-hydroxy-3-methyl-2,5-dihydro-1-benzoxepin-7-carboxylic acid (2), were synthesized using Stille coupling followed by Mitsunobu cyclization.

A versatile strategy to halogenated xanthones was developed that relies on a modular coupling of vanillin derivatives with a dibromoquinone. Depending on the reaction conditions, either the 6- or the 7-bromo heterocycles may be obtained in a divergent manner. These heterocycles may be readily further elaborated by sequential Sonogashira couplings, and the sequence may be successfully applied to substructures
