A green synthesis of 3,4-dihydropyrimidine-2(1H)-one/thione derivatives using nanosilica-supported tin(II) chloride as a heterogeneous nanocatalyst

A green synthesis of 3,4-dihydropyrimidine-2(1H)-one/thione derivatives using nanosilica-supported tin(II) chloride as a heterogeneous nanocatalyst

Efficient, green, and straightforward synthesis of 3,4-dihydropyrimidine-2(1 H )-one/thione derivatives under favorable conditions has been achieved by reaction of urea/thiourea, aldehydes, and ethyl acetoacetate, using the synthetic potential of nanosilica-supported tin(II) chloride. It is notewort...

Zusammenfassung:Efficient, green, and straightforward synthesis of 3,4-dihydropyrimidine-2(1 H )-one/thione derivatives under favorable conditions has been achieved by reaction of urea/thiourea, aldehydes, and ethyl acetoacetate, using the synthetic potential of nanosilica-supported tin(II) chloride. It is noteworthy that the procedure has many advantages, for example excellent product yields, short reaction time, easy isolation of products, and reusability of catalyst. Graphical Abstract .
