The disclosure provides compounds, compositions and methods using these compounds and compositions to stimulate the differentiation of cells and inhibit excessive cell proliferation of certain cells, including cancer cells and skin cells, which may be useful in the treatment of diseases characterized by abnormal cell proliferation and/or cell differentiation such as leukemia, myelofibrosis and psoriasis without the well known effect on calcium metabolism, which gives rise to hypercalcemia.
Anodic Oxidation of Ketone Allylhydrazones into the Corresponding Azines
Abstract Several ketone allylhydrazones were electrochemically oxidized in methanol in the presence of sodium methoxide and potassium iodide to afford the corresponding azines. The electro-oxidation involves formation of a new carbon–nitrogen double bond between an allylic carbon atom and the nitrogen atom of a hydrazone to afford a conjugated system. Optimal yields were obtained when 0.5 equivalents
