In this study, we executed an effective and novel enantioselective Michael/cyclodehydration sequential reaction between pyrazolin-5-one (or 4-hydroxy-2-pyrone) and chalcones that is catalyzed by a quinine-derived primary amine L7 in the presence of B

A simple and highly atom-economical method for the direct N-alkylation of aromatic amines by using a microflow reactor was developed to overcome the problem of over-alkylation. In the developed method, high-yield conversion (up to 100%) was achieved

A series of mansonone F (MF) derivatives were designed and synthesized. These compounds were found to be strong inhibitors for topoisomerases, with much more significant inhibition for topoisomerase II rather than topoisomerase I. The best inhibitor

This report describes the efficient synthesis of quercetin 3-O-[6″-O-(trans-p-coumaroyl)]-β-D-glucopyranoside 1 (isoquercitrin coumarate), an acylated quercetin glycoside possessing antihypertensive, antidiabetic, and tyrosinase inhibitory activit

Dimethylaluminium methaneselenolate (Me 2 AlSeMe, 1) acts as an acyl transfer agent for esterification. In cases of direct macrolactonisation (n = 10-12), this selenium-aluminium complex preferentially creates symmetric macrodiolides rather than macr
