“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 کاملMicroencapsulation of Dragon Fruit (Hylocereus polyrhizus) Peel Extract Using Maltodextrin
Dragon fruit peel can be utilized as a natural dye due to betacyanin content, redviolet pigment of betalain group. Betacyanin is unstable to temperature, oxygen, and light, consequently microencapsulation technology is required to maintain its stability. This study aims to determine microencapsulation efficiency of dragon fruit peel extract with variation of encapsulation ratio and to perceive ...
متن کاملWaugh Type Enneamolybdomanganate(IV) Catalyzed Synthesis of Polyhydrquinoline Through Hantzsch Multi-Component Condensation
An efficient one pot coupling of aldehydes, dimedone, ammonium acetate and ethyl acetoacetate by using catalytic amount of enneamolybdomanganate(IV) is reported. Various polyhydroquinoline derivatives have been prepared in high yields and comparatively less reaction time.
متن کاملP-TSA catalyzed facile and efficient synthesis of polyhydroquinoline derivatives through hantzsch multi-component condensation.
A facile and efficient synthetic route to polyhydroquinolines has been developed via four-component condensation reactions of aldehydes, dimedone, ethyl acetoacetate and ammonium acetate in the presence of p-toluenesulfonic acid (p-TSA) catalyst in ethanol at ambient temperature through Hantzsch reaction. Simple work-up procedure, environmentally friendly, inexpensive and non-toxic catalyst, sh...
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
