An efficient synthesis of 2‐amino‐4a,5,6,7‐tetrahydronaphthalene‐1,3,3(4H)‐tricarbonitriles via the tandem four‐component condensation of one equivalent of aromatic aldehyde, cyclohexanone, and two equivalents of malononitrile in ionicliquids was undertaken. Up to four new bonds and one new ring were formed in one‐pot with water as the only by‐product in this multi‐component procedure.

AbstractHerein, we report a novel method for synthesis of bicyclic ortho-aminocarbonitriles catalyzed by biodegradableionicliquid. The biodegradability (BOD analysis) of all the ionicliquids that are used to carry out the reaction is studied, and these ester-functionalized ionicliquids showed better degradability as compared to the rest of the ILs. The IL used in the reaction was recycled six times

spiroacenaphthylene, benzo[α]cyclooctenes, etc. Therefore, development of an efficient method for a MCR which encompass vinylogous Michael addition as vital reaction is of current interest. Methods: We explored catalytic efficiency of DABCO in the multi-component reaction of cyclic ketone, aldehyde and two moles of malononitrile for the synthesis of functionalized condensed bicyclic compounds viz tetrahydroindenes

Abstract In this research, the treatment of cyclohexanone, malononitrile, and aromatic aldehydes was carried out for the successful synthesis of orthoaminocarbonitrile tetrahydronaphthalenes by using butyl-3-methylimidazolium hexafluorophosphate as a base catalyst. In this protocol, the target products were obtained in high to excellent yields between 85% and 95% and short reaction times between 10

Mesoporous yolk–shell nanocomposites (MYSNs) were loaded with a mobile CaMg core inside the silica shell. CaMg@MYS nanocomposites have been effectively prepared inside the inner cavity of a novel structure that consists of hollowmesoporous silica spheres. Tetraethyl orthosilicate (TEOS) and an amount of cetyltrimethylammonium bromide (CTAB) are coated on the carbonspheres used as a hard template
