Described are compositions comprising a muscarinic receptor antagonist and an N-acylated heterocycle derivative having affinity for serotonergic receptors, and enantiomers, diastereoisomers, N-oxides, polymorphs, solvates and pharmaceutically acceptable salts thereof. The combination of a muscarinic receptor antagonist and an N-acylated heterocycle, or an enantiomer, diastereoisomer, N-oxide, polymorph, solvate or pharmaceutically acceptable salt thereof, is useful in the treatment of patients with neuromuscular dysfunction of the lower urinary tract and diseases related to 5-HT

A novel route is disclosed for the synthesis of 1,2,4-thiadiazoles starting from amidines, elementalsulfur, and 2-methylquinolines or aldehydes under transition-metal-free conditions. This three-component approach affords efficient and rapid access to 3,5-diaryl substituted 1,2,4-thiadiazoles with good tolerance of a broad range of funcitional groups. Mechanistic studies reveal a radical-involved

Herein, we describe the enantioselective C(sp3)–H bond functionalizations of 2-alkyl azaarenes using a cooperative dual Lewis acid catalysis. An achiral Lewis acidactivates the unactivated azaarene partner without the need for a strong base. Orthogonally, a chiral-at-metal Lewis acidcatalyst enables LUMO lowering and induces chirality. This method tolerates a range of complex molecular scaffolds
