N -(Sulfonamido)alkyl[tetrahydro-1 H -benzo[ e ]indol-2-yl]amines: potent antagonists of human neuropeptide Y Y5 receptor
摘要:
[3a,4,5,9b-Tetrahydro-1H-benzo[e]indol-2-yl]amines were prepared via reductive amination and concomitant cyclization of alpha-cyanomethyl-beta-aminotetralins. N-acylation with Omega-sulfonamido-carboxylic acids and subsequent reduction afforded a series of N-(sulfonamido)alkyl[tetrahydro-1H-benzo[e]indol-2-yl]amines, which bound to the human neuropeptide Y Y5 receptor with nanomolar affinity.

Bifunctional Brønsted Base Catalyst Enables Regio-, Diastereo-, and Enantioselective C<sub>α</sub>-Alkylation of β-Tetralones and Related Aromatic-Ring-Fused Cycloalkanones
The catalyticasymmetric synthesis of both α‐substituted and α,α‐disubstituted (quaternary) β‐tetralones through direct α‐functionalization of the corresponding β‐tetralone precursor remains elusive. A designed Brønsted base‐squaramide bifunctionalcatalyst promotes the conjugate addition of either unsubstituted or α‐monosubstituted β‐tetralones to nitroalkenes. Under these reaction conditions, not
