“On-Water” Catalyst-Free Ecofriendly Synthesis of the Hantzsch Dihydropyridines
An eco-friendly "on-water" protocol for efficient catalyst-free synthesis of the Hantzsch dihydropyridines from aryl, heteroaryl, alkyl, and vinylogous aldehydes has been developed with minimum auxiliary substances, toxic reagents, organic solvents, and disposal problems.
متن کاملOxidation of Hantzsch 1,4- Dihydropyridines to Pyridines with Thallium Triacetate
Hantzsch 1, 4-dihydropyridines (1,4-DHPs) can be oxidized to the corresponding pyridine derivatives by thallium triacetate in high yields.
متن کاملAROMATIZATION OF HANTZSCH 1,4- DIHYDROPYRIDINES WITH ZINC CHLOROCHROMATE NONAHYDRATE
Hantzsch 1 ,4- dihy&opyridines are rapidly oxidized to the corresponding pyridine derivatives using zinc chlorochromate nonahydrate [Zn(C1CrO ) .9H O] in dichloromethane at room temperature. In addition to aromatization, no loss of the 4- substituent is observed
متن کاملStable reagents for determination of serum triglycerides by a colorimetric Hantzsch condensation method.
We describe a modified method for determining triglycerides in serum, in which alumina is used to adsorb interfering substances, and the glycerol content of triglycerides is determined colorimetrically. In contrast to all previous Hantzsch condensation procedures in which periodate and acetylacetone are used, the working periodate and the working acetylacetone reagents are stable for at least s...
متن کاملFeNH4(SO4)2·12H2O (alum)-catalyzed preparation of 1,4-dihydropyridines: improved conditions for the Hantzsch reaction
ABSTRACT FeNH4(SO4)2·12H2O (alum) efficiently catalyzes the one-pot three-component reaction of dimedone, aldehydes, and 3-aminocrotonate to afford 1,4-dihydropyridines. The work-up is easy, and the products are obtained in good to excellent yields and high purity. GRAPHICAL ABSTRACT
