日期:2016.8
A convenient and efficient organocatalytic procedure for the selective cyclization of 1,3-diketones to give aromatic substituted 4H-chromen-4-ones under mild reaction conditions using N-triflyl phosphoramide is described. Application of the described conditions is presented in a formal synthesis of (S)-flavanone.

A one-potsynthesis of novel benzopyran-4-ones is described. In a tandemreaction, organobase-catalysed Michaeladdition of (RCOCH2COR2)-C-1 on chromone-3-carboxylic acid led to decarboxylation and pyran-4-one ring opening of the latter. This was followed by chromone- and/or chromanone ring closure of the resulting Michael adducts when R-1 is an ortho-hydroxyaryl group. Antioxidant testing of 14 derivatives
Muscarinic acetylcholine receptor-active compounds have potential for the treatment of Alzheimer’s disease. In this study, a series of natural and synthetic flavones and flavonols was assayed in vitro for their ability to inhibit radioligand binding at human cloned M1 muscarinic receptors. Several compounds were found to possess competitive binding affinity (Ki = 40–110 µM), comparable to that of acetylcholine (Ki = 59 µM). Despite the fact that these compounds lack a positively-charged ammonium group under physiological conditions, molecular modelling studies suggested that they bind to the orthosteric site of the receptor, mainly through non-polar interactions.
