Synthesis of 8-Bromo-1, 2, 3, 4-tetrahydro-1-[p-(5-hydroxymethyl-2-methoxy-phenoxy)benzyl]-6, 7-methylenedioxyisoquinoline : Studies on the Heterocyclic Compounds CCXXV

Synthesis of new polyurethanes based on 5, 6, 7, 8 – tetrabromo – 2, 3 – dihydro – 1, 4 – phthalazine dione

In this work, 5,6,7,8-Tetrabromo-2,3-dihydro-2,3-bis(2-hydroxyethyl)phthalazine-1,4-dione is synthesized by the reaction of 5,6,7,8-tetrabromo-2,3-dihydrophthalazine-1,4-dione with 2-bromoethanol in the presence of triethylamine. The obtained monomer was polymerized with different diisocyanates, including hexamethylenediisocyanate (HMDI), tolylene-2,4-diisocyanate (TDI), isophoronediisocyanate ...

SYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID

Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...

27 A 3,204 bp full-length cDNA of bovine NALP9 was cloned and its genomic organisation was 28 analyzed. The 2,988 bp open reading frame covers 9 exons and encodes a deduced protein of 996 29 amino acids containing Pyrin, Nacht and leucine-rich repeat domains like the human NALP gene 30 family members. Mapping with the WGRH5000 panel and fluorescence in situ hybridisation 31 assigned NALP9 in cl...

A decentralized failure detection and isolation (FDI) methodology, which is robust with respect to model uncertainties and noise, is presented. Redundancy metrics are developed, and optimization problems are posed for the choices of robust parity relations. Closed-form solutions for some special failure cases are given. Connections are drawn with other disciplines, and the use of the metrics to...
