In contrast, amide formation is the most-used bond construction in medicinal chemistry because the chemistry is reliable and draws upon large, diverse substrate pools. A new method for the synthesis of ketones is presented here that draws from the same substrates used for amide bond synthesis amines and carboxylic acids. A nickel terpyridine catalyst couples N -alkyl pyridinium salts with in-situ formed carboxylic acid fluorides or 2-pyridyl esters under reducing conditions (Mn metal). The reaction has broad scope, as demonstrated by the synthesis of 35 different ketones bearing a wide variety of functional groups with an average yield of 60 ± 16%. This approach is capable of coupling diverse substrates, including pharmaceutical intermediates, to rapidly form complex ketones. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematologic malignancy arising from plasmacytoid dendritic cell precursors. The disease typically manifests in the skin, but it also evolves into a leukemic phase or can be complicated by other myeloid malignancies, especially myelomonocytic tumors. The association between these neoplasms is not fully elucidated. We report a case of BPDCN with a history of cytopenia that was supposed to be chronic myelomonocytic leukemia. The patient received intensive chemotherapy and achieved complete remission, but soon relapsed. The successive
