Synthesis of new 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone moiety containing 4-thiazolidinone moiety

A series of novel 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone framework (4a-f) were synthesized through a four-step reaction starting from the reduction of nitro derivatives of 1, 8-dioxo-octahydroxanthenes. The resulting aminoxanthenes converted to thiourea derivatives via their reaction with methyl isothiocyanate. The final products were synthesized through the re...

Lecture 8 : December 27 , 2001

Phylogenetics is the area of research concerned with finding the genetic relationships between species. The basic idea is to compare specific characters (features) of the species, under the natural assumption that similar species (i.e., species with similar characters) are genetically close. The term phylogeny refers to these relationships, usually presented as a phylogenetic tree (see Figures ...
