Catalytic Photochemical Enantioselective α-Alkylation with Pyridinium Salts
, 2022 We have developed a chiral amine catalyzed enantioselective α-alkylation of aldehydes with amino acid derived pyridinium salts as alkylating reagents. The reaction proceeds in the presence of visible light (390 nm) and in the absence of a photocatalyst ...

Synthesis and structure of novel tripodal ligands based on tetrazol-5-thioles
Журнал Белорусского государственного университета: Химия, 2022 Novel tripodal ligands (R1N4CS)3CH, where R1 = Me, Ph, were synthesised by alkylation of 1-R-tetrazol-5-thioles with iodoform in alkaline media. These ligands were identified based on data of elemental analysis, nuclear magnetic resonance spectroscopy ...
