NEW COMPOUND

PROBLEM TO BE SOLVED: To provide a new compound that does not have structural similarity to ceramide and has excellent CERT inhibitory activity. SOLUTION: The present invention provides a new compound of structural formula (I). A bond group -X- is cis-cyclopropyl-, R1, R2, R3, R4, and R5 independently represent a hydrogen atom, a halogen atom, a linear or branched C1-C8 alkyl group that may have a halogen atom, or OR6.

Regioselective dinitration of simple aromatics over zeolite Hβ/nitric acid/acid anhydride systems

Various nitration systems comprising nitric acid, acid anhydride and zeolite H￡] in the absence of solvent are described. Direct double nitration of toluene with a nitric acid, propanoic anhydride and zeolite Hβ system has been developed to give 2,4-dinitrotoluene in 98% yield, with a 2,4-:2,6-dinitrotoluene ratio of 123:1. This system also nitrates activated mono-substituted benzenes (anisole and phenetole) and moderately activated mono-substituted benzenes (ethylbenzene and propylbenzene) to give mainly 2,4-dinitro derivatives. The zeolite can be recovered, regenerated and reused to give almost the same yield as that given when fresh zeolite is used. ARKAT-USA, Inc.

METHODS FOR THE NITRATION OF AROMATIC COMPOUNDS

According to the invention there is provided a method for the nitration of an aromatic compound including the step of reacting the aromatic compound with nitric acid in the presence of an acid anhydride and an aluminosilicate catalyst, in which the acid anhydride is at least one of: ((CnH2n+1)CO)20, where n is 1 to 4 and the moiety CnH2n+1 can be straight or branched chain; ((CHpClq)CO)20, where p is 0 to 2, q is 1 to 3, and p+q = 3; and oxoiane -2, 5-dione, with the proviso that when the acid anhydride is (CH3CO)20, the aromatic compound is toluene, 2-nitrotoluene or 4-nitrotoluene, and the nitration is performed to produce 2,4-dinitrotoluene.
