bearing a single stereocenter or adjacent stereocenters. Herein, we report an enantio- and diastereoselective synthesis of substituted chiral allenes with nonadjacent axial and two central chiral centers through a combination of retro-oxa-Michael addition and palladium-catalyzed asymmetric allenylic alkylation. This methodology exhibits good functional-group compatibility, and the corresponding allenylic

used for leukaemia treatment, their low stability in physiological conditions and their lack of selectivity arise the need for the identification of non-nucleoside DNA methyltransferase inhibitors. Here, we describe the synthesis and pharmacological characterisation of a novel class of DNA methyltransferase inhibitors: the 3-halo-3-nitroflavanones. We showed that 3-bromo-3-nitroflavanones 3b and 4a have
