organic photocatalyst, and we describe a robust method for the directC(sp3)–H carbamoylation of saturated aza-heterocycles under mild conditions by using a naphthalimide (NI)-based organic photocatalyst. This protocol provides a concise and practical approach for the rapid installation of a valuable amide bond onto pharmaceutically useful saturated aza-heterocycles to access a wide range of cyclic α-amino

a novel and efficient α-C(sp3)–H alkenylation of cyclic amines with maleimides. Mechanistically, this C(sp3)–H/C(sp2)–H cross dehydrogenative coupling (CDC) reaction involves a cascade procedure including oxidative α-amino radical formation from the cyclic amine substrate and nucleophilicaddition of the in situ formed α-amino radical onto the electron-deficient carbon–carbon double bond of maleimide

Compounds that may be used to inhibit Notum Pectinacetylesterase are described, as well as compositions comprising them, and methods of their use to treat diseases and disorders affecting bone.
were established. The mild reaction conditions make this approach an appealing and versatile strategy to functionalize/oxidize pyrrolidines whereby arylsulfonyl chlorides were identified to be both catalyst regeneration and sulfonylation reagents.
Novel substituted piperidines of the general formulae (I) and (II) with the substituent definitions as explained in detail in the description are described. The compounds are suitable in particular as renin inhibitors and are highly potent.
