Synthesis of Diverse Boron-Handled N-Heterocycles via Radical Borylative Cyclization of N-Allylcyanamides
摘要:
A synthetic method based on radical borylation/cyclization cascades of N-allylcyanamides was developed to construct diverse boron-substituted N-heterocycles. In the reaction process, the N-heterocyclic carbene-boryl radical underwent a chemo- and regioselective addition to the alkene moiety, followed by cyclization with the N-cyano group. The resulting amide-iminyl radical intermediates underwent further reactions to afford various boron-tethered N-heterocyclic molecules. Further transformations to access synthetically useful building blocks were also demonstrated.

This invention discloses a novel arylaminomethyl propenyl benzhydroxyamide derivative of formula (I) useful for preventing or treating various diseases induced by histone deacetylase, a method for preparing same and a pharmaceutical composition comprising same.
Muscarinic acetylcholine receptors (mAChRs) comprise five distinct subtypes denoted M1 to M5. The antagonism of M2 subtype could increase the release of acetylcholine from vesicles into the synaptic cleft and improve postsynaptic functions in the hippocampus via M1 receptor activation, displaying therapeutic potentials for Alzheimer’s disease. However, drug development for M2 antagonists is still challenged
An efficient synthesis of highlysubstitutedisoquinoliniumsalts from ketimines and alkynes via a Rh(III)-catalyzed C-H bond activation and annulation reaction is described.

compared with the reference drug against the tested microorganisms. Although, 3j was less active among its analogues to inhibit the breast carcinoma cells, it exhibit strong broad spectrum antimicrobial activities. However, The results of the cytotoxic activity revealed that compound 3p was the most active against the breast carcinoma cell line (MCF-7) giving promising IC50 value of 1.72 μg/mL, compared with
