The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Chaitanya, Muggu V. S. R. K., once mentioned the application of 16415-12-6, Name is Hexadecyltrimethoxysilane. Now introduce a scientific discovery about this category, Category: naphthyridines.
Microwave-assisted synthesis of naphthyridinoylpyrazolidinones (7a-7j) has been achieved rapidly via the reaction of naphthyridine hydrazide (4) with different beta-keto esters and ethoxymethylenemalonic ester (EMME) (5a-5e). Initially, the reaction of naphthyridine hydrazide (4) with various beta-keto esters under microwave irradiation for 5 mins at 130 degrees C results in the formation of condensed products 6a-6j. This condensation was followed by cyclization, also, in diphenyl ether under microwave irradiation for 10 mins at 230-250 degrees C, yielding the corresponding cyclized products 7a-7j. Alternatively, both reactants 4 and each of the beta-keto esters/EMME (5a-5e) were treated in diphenyl ether under microwave irradiation for 15 mins at 230-250 degrees C giving the target molecules 7a-7j as one-pot reaction in good yields.
The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states. I hope my blog about 16415-12-6 is helpful to your research. Category: naphthyridines.
