Organocatalysis
During the past 12 years or so, hardly any other field has impacted the art and science of chemical synthesis more profoundly than organocatalysis. The growth, both in academic research and in industrial use, has been breathtaking. Judging by the development of its impact factor, the Beilstein Journal of Organic Chemistry is currently attempting to achieve the same impact within chemistry publi...
متن کاملtitrimetriC aSSay of liSinopril in aqueouS and non-aqueouS media
Four simple titrimetric procedures are described for the determination of lisinopril (LNP) in bulk and in pharmaceuticals based on the neutralization of basic-amino and acidic carboxylic acid groups present in LNP. Method A is based on the neutralization of basic amino groups using perchloric acid as titrant in anhydrous acetic acid medium. Method B, method C and method D are based on neutraliz...
متن کاملCyclic Oligophosphonic Anhydrides Stable in Aqueous Media
Depending on reaction conditions, the phosphonylation of N-alkylacetamides with H3PO3-P C I3 in B-HC1 media (B = Py, Bu3N) gives either l-alkylaminoethylidene-l,l-bisphosphonic acids (la—e) or previously unknown l-alkylaminobutane-l,l,3,3-tetrayl-tetrakisphosphonic dianhydrides (2a-e). The latter convert into monocyclic forms (3a-e) under mild acidic hydrolysis. Acyclic forms (4a-e) cannot be i...

متن کاملKinetic characterization of spiropyrans in aqueous media.
Detailed kinetic investigations of the most common photoswitchable spiropyran, 6-nitro-BIPS, reveal that hydrolytic decomposition of its merocyanine isomer limits its utility in aqueous buffer; however, simple replacement of the 6-nitro substituent with an 8-carboxylate yields a BIPS photoswitch that is potentially better suited for biological applications.
