چکیده

In the racemic title compound, C16H14O3, the ring of the 4-hy-droxy-benzyl substituent group forms a dihedral angle of 80.12 (12)° with the benzene ring of the chromanone system. Two C atoms of the pyran-one ring and the H atoms on the benzyl α-C atom are disordered over two sites, with site-occupation factors of 0.818 (8) and 0.182 (8). The crystal structure is stabilized by O-H⋯O hydrogen bonds, which form parallel one-dimensional zigzag chains down the c axis and are inter-connected by both methine C-H⋯O hydrogen bonds and weak aromatic C-H⋯π inter-actions, giving a sheet structure lying parallel to [011].

Homoisoflavanones from Agave tequilana Weber.

Three homoisoflavanones were isolated from the "piña" and leaves of Agave tequilana Weber. The compounds were identified as: 5,7-dihydroxy-3-(4-methoxybenzyl)-chroman-4-one (1), 7-hydroxy-3-(4-hydroxybenzyl)-chroman-4-one (2) and 4'-demethyl-3,9-dihydro-punctatin (3). This is the first phytochemical study carried out to Agave tequilana Weber.

Design, Synthesis, and Evaluation of Functionalized Chroman-4-one and Chromone Derivatives Somatostatin receptor agonists and Sirt2 inhibitors

Peptides are involved in many physiological processes such as regulation of blood-pressure, food intake, pain transmission and blood-glucose levels. They consist of amino acids that are connected through amide bonds which make peptides hydrophilic and conformationally flexible. Peptides generally make poor oral drugs as amide bonds are easily cleaved by endogenous enzymes. One way to overcome t...

Tandem Alkyne Hydroacylation and Oxo-Michael Addition: Diastereoselective Synthesis of 2,3-Disubstituted Chroman-4-ones and Fluorinated Derivatives.

Tandem reactions involving Rh-catalyzed intermolecular hydroacylations of alkynes with salicylaldehydes followed by intramolecular oxo-Michael additions are described for the diastereoselective synthesis of 2,3-disubstituted chroman-4-ones. The tandem hydroacylation/oxo-Michael additions occur to form 2,3-disubstituted chroman-4-ones in high yields from a range of 1,2-disubstituted acetylenes a...
