relevant molecules bear nitrogen and sp3-hybridized carbon functionalities. Overwhelmingly, these atoms are found as part of (hetero)cyclic structures. Despite their importance, syntheticapproaches to saturated nitrogen heterocycles are limited to several established stoichiometric alkylation techniques, as well as a few methods involving C-H bond activation. The synthetic community remains interested

Substituted piperazines and morpholines are valuable structural motifs in biologically active compounds, but are not easily prepared by contemporary cross-coupling approaches. In this report, we introduce SnAPreagents for the transformation of aldehydes into N-unprotectedpiperazines and morpholines. This approach offers simple, mild conditions compatible with aromatic, heteroaromatic, aliphatic,

available SnAP (stannyl amine protocol) reagents allow the transformation of aldehydes and ketones into a variety of N‐unprotected heterocycles. By identifying new ligands and reaction conditions, a robust catalytic variant that expands the substrate scope to previously inaccessible heteroaromatic substrates and new substitution patterns was realized. It also establishes the basis for a catalytic enantioselective

Photocatalytic coupling of aldehydes and silicon amine protocol (SLAP) reagents enables the simple, scalable synthesis of substituted morpholines, oxazepanes, thiomorpholines, and thiazepanes under continuous flow conditions. Key to the success of this process is the combination of an inexpensive organic photocatalyst (TPP) and a Lewis acid additive, which form an amine radical cation that is easily
