Magic of natural material in organic transformations

Consumption of natural material as a catalyst obtained from natural sourced material and some novel sulfonic acid functionalized ionic liquids, as a new category of Bronsted acidic ionic liquid explained for heterocyclic synthesis which covers the maximum principles of green chemistry. This book presents, Bael Fruit Ash Water Extract (BFAWE) as a natural sourced base catalyst for the synthesis of 2-amino-4H-benzochromenes and tetrahydro chromeno [4,3-b] chromene-6,8-diones. And [BBSA-DBU] [HSO4]: A novel ionic liquid for synthesis of Xanthenes, pyrazolopyranopyrimidines and quinoxaline.The use of BFAWE for organic transformation is used to remove of corrosive catalysts and toxic reagents. Ionic liquids have been considered as green alternatives to volatile organic media because of their negligible vapor pressure and non-flammable nature. The other advantages of reported methods included highly efficient, easily available, better yield of product obtained in a short reaction time, reuse of catalyst for several times. This book divides in to six topics. At the end of topic spectra and spectral data of all synthesized compounds are reported.
