It relates to the compounds of formula (I), or their pharmaceutically or veterinary acceptable salts, or their stereoisomers or mixtures thereof, wherein A, R1, R2, and R3 are as defined herein, which are inhibitors of one or more DNMTs selected from the group consisting of DNMT1, DNMT3A and DNMT3B. It also relates to pharmaceutical or veterinary compositions containing them, and to their use in medicine, in particular in the treatment and/or prevention of cancer, fibrosis and/or immunomodulation.

methods for the preparation hinder their widespread application. Herein, we report that nitroenamines undergo electrochemical cyclisation to 3-nitroindoles in the presence of potassium iodide. Detailed control experiments and cyclic voltammogram studies infer the reaction proceeds via a sequential paired electrolysis process, beginning with anodic oxidation of iodide (I−) to the iodine radical (I˙),

The invention relates to novel oxazine derivatives of formula (I), and pharmaceutically acceptable salts thereof, in which all of the variables are as defined in the specification, pharmaceutical compositions thereof, combinations thereof, and their use as medicaments, particularly for the treatment of Alzheimer's Disease or diabetes via inhibition of BACE-1 or BACE-2.
value of the methodology described is demonstrated by providing (a) a direct route for the asymmetricsynthesis of differently substituted 1,2-diamines and (b) a new asymmetricsynthesis of gamma-amino alpha,beta-unsaturated esters through a catalytic, highly enantioselective formal addition of functionalized alkenyl groups to azomethines. Finally, a preferred TS that nicely fits the observed enantioselectivity

The syntheses of D,L-deoxyribose, D,L-oleose, D,L-digitoxose, D,L-2-deoxygalactose, 1,3-dideoxyfructose, 3-deoxyfructose etc. are described. Basic aluminum oxide is introduced as a solid phase base for the one step synthesis of 2-isoxazolines from aldoximes and
