Synthesis of 1,4-Dihydropyridines Bearing a Carbamate Moiety on the 4-Position

Journal of Chemistry, 2013
A good range of 1,4-dihydropyridines bearing a carbamate moiety on the 4-position were synthesized from the primary reaction of different hydroxyaldehydes with phenyl isocyanates and the subsequent reaction of the obtained carbamates with methyl ...

One-Pot Synthesis of 1, 4-Dihydropyridines in PEG Under Catalyst-Free Conditions [PDF]

Advances in Engineering Research, 2015
A simple, inexpensive, and efficient one-pot synthesis of 1,4-dihydropyridine via Hantzsch reaction was achieved in good to excellent yields under catalyst free conditions by using PEG400 as solvent. In this reaction, PEG-400 was used as the solvent, which has such advantages: absolutely nontoxic, inexpensive, thermally stable, recoverable and easy to ...

Impact of empiric potassium supplementation on mortality, sudden cardiac arrest and stroke in furosemide initiators

British Journal of Clinical Pharmacology, EarlyView.
Aim A prior non‐randomized study suggests that potassium supplementation may improve survival among furosemide initiators, and a randomized trial suggests that salt substitutes containing potassium might lower stroke risk. We conducted a retrospective cohort study using health‐care data to confirm or refute these associations among new users of ...
