Mesoporous KIT-6 supported ionic liquids as new and highly effective heterogeneous catalysts for three-component synthesis of 2-amino-3-cyano-4H-pyrans

A series of mesoporous KIT-6 supported ionic liquids were prepared and tested as effective and practical catalysts for the synthesis of 2-amino-3-cyano-4H-pyrans. The effects of type of catalysts, catalyst amount, and catalyst stability have also been inv

The invention discloses a synthesis method of 2-amino-4H-pyran and a derivative of the 2-amino-4H-pyran. According to the method, candida rugosa lipase (CRL) is adopted as a catalyst to initiate a tandem MCR reaction, and 2-amino-4H-pyran is synthesized i

Synthesis of novel multi-OH functionalized ionic liquid and its application as dual catalyst-solvent for the one-pot synthesis 4H-pyrans

In the present work, triethanolammonium 3-hydroxypropane-1-sulfonate [TEA][HPS] as a novel multi-OH functionalized ionic liquid was synthesized. [TEA][HPS] was characterized by 1HNMR, 13CNMR, FT-IR and elemental analysis. In addition

Synthesis, biological evaluation and molecular docking study of 1,2,3-1H-triazoles having 4H-pyrano[2,3-d]pyrimidine as potential Mycobacterium tuberculosis protein tyrosine phosphatase B inhibitors

Some heterocycles, namely 2-amino-4H-pyran-3-carbonitriles, were synthesized in a three-component reaction from substituted benzaldehydes, malononitrile, and ethyl acetoacetate. These heterocycles have been converted subsequently into 4H-pyrano[2,3-d]pyri

DABCO catalyzed green and efficient synthesis of 2-Amino-4H-Pyrans and their biological evaluation as antimicrobial and anticancer agents

Aim and Objective: The present method is simple, green and highly efficient for the synthesis of 2-amino-4H-pyran derivatives which are achieved by a one pot three component cyclocondensation of aldehyde, malanonitrile and ethyl acetoacetate or methyl acetoacetate using DABCO under solvent free with grinding conditions at room temperature. Material and Methods: Some of the synthesized compounds were screened for their antimicrobial and antifungal activity. The study shows that these compounds show good antimicrobial activity. Furthermore, eight of the synthesized compounds were selected for screening of their anticancer activity against human astrocytoma-glioblastoma cell line (U373MG). Some of the compounds show good anticancer activity. Result: Grinding synthesis of 2-amino-4H-pyran derivatives catalyzed by DABCO with various aromatic aldehydes under solvent-free conditions at room temperature was examined. The obtained compounds (22 entries) were well synthesized in good to excellent yields. Conclusion: The present method is simple, rapid, and most efficient green protocol for the synthesis of 2-amino-4H-pyran derivatives using highly inexpensive and easily available DABCO as an efficient catalyst under grinding and solvent free condition at room temperature.

New application of decaniobate salt as basic solid in the synthesis of 4H-pyrans by microwave assisted multicomponent reactions

This study focuses on the search of new applications of polyoxometalates known as decaniobate ions [Nb10O28]6?. The decaniobates can be used as basic solid catalysts in multicomponent reactions to obtain good yields to 4H-pyrans (> 95%) under microwave radiation and solvent-free conditions, using several aldehydes with different electron-withdrawing or electron donor substituents. The synthesis of (TMA)6 [Nb10O28]6H2O was performed following a simple protocol (HPNb), which was modified to decrease the number of hexaniobate species that are formed as impurities (HPNb-HF).
