New Synthesis ofβ-Anilinochalcones by Regioselective Oxidation ofβ-Anilinodihydrochalcones Using Iodine–DMSO
摘要:
beta-Anilinodihydrochalcones readily undergo oxidation alpha to the carbonyl group region in the presence of a catalytic amount of iodine in dimethyl sulfoxide at 130 degrees C in good yield. Oxidation of allyloxy-substituted beta-anilinodihydrochalcones to beta-anilinochalcones is a preferred reaction over deallylation.

affinity binding to androgen receptors, agonist and/or antagonist activities in both CV-1 and MDA-MB-453 transfection assays. A proliferation assay in LNCaP cells also exhibited this profile. A representative of these non-steroidal compounds (compound 21) was devoid of activity at other nuclear receptors (oestrogen, progesterone, glucocorticoid and mineralocorticoid receptors) in the CV-1 co-transfection

AbstractSnCl2-catalyzed three-component one-pot Mannich reaction of acetophenone or p-chloroacetophenone with different aromaticaldehydes and aromatic amines in ethanol at ambient temperature gave the corresponding β-aminocarbonyl compounds in good to excellent yields. Four new compounds are reported for the first time. Graphical abstract

describe the development of the first enantioselective Bronsted acid assisted chiral Bronsted acidcatalyzed direct Mannichreaction of acetophenone with various aldimines. The reaction proceeds in the presence of a chiral and an achiral Bronsted acid which simultaneously activate the ketone and aldimine to give the corresponding p-amino ketones with good enantioselectivities and without the necessity of enolate
