An unusual addition of enamines to chromone‐substituted acrylic acid is an efficient and versatile method of synthesis of allylamine derivatives. The reaction is catalyzed by amines and is highly likely of Morita–Baylis–Hillman‐type. The described compounds show combined moderate inhibitory action on BChE and antagonism towards NMDA receptors

The [4+2] cycloaddition of chromone-fused dienes with enamines was found to be an efficient method for the synthesis of 4,4a- and 3,4-dihydroxanthone derivatives. Either product type could be obtained by choosing the proper conditions [reaction time and addition of La(NO3)3 as a Lewis acid]. Calculations using density functional theory and Møller–Plesset perturbation theory showed that the isomerization
A visible-light-driven, photocatalyst-free, air-assisted carbon cleavage of dienes was achieved. Photochemical editing of dienes via an electron donor–acceptor (EDA) complex facilitates direct access to cyclopropane derivatives. This innovative methodology creates an opportunity for the efficient access to valuable cyclopropane derivatives under mild and ambient conditions.

developed novel chromone-containing analogues with embedded acrylate fragment as potential PL inhibitors. The analogues were designed by considering the structural features required for binding at the active site of PL enzyme with the utilization of molecular docking study. An optimized synthetic scheme was utilized for the synthesis of designed analogues of prototypes 1&2. Through in vitro PL inhibitory
