Current Organic Chemistry - Volume 8, Issue 15, 2004

Prebiotic chemistry plays a central role in the investigation of the possible scenarios of the early chemical environments. Its goal is to shed light on the events involved in the synthesis of initial biomolecules and on the selforganization processes that led the last common ancestor. Even though a well defined scenario for the physicochemical conditions on the primitive Earth is not available, one can assume that a synthetic pathwa Read More

Selected examples of cyclodextrin (CD) oligomers have been presented, describing their syntheses, physicochemical properties and application possibilities. The first part of the review concerns CD dimers, the second one deals with CD trimers and tetramers. The references are cited mainly of reports that appeared during the years 2001-2003.

Although Fischer obtained the first pyridazines as early as 1886, major attention has been devoted to their chemistry only in the early few decades. However, pyridazin-3(2H)-ones and their fused ring derivatives have recently received much more attention to possess various biological activities and also to use new synthetic auxiliaries. The scope of the present review is to summarize from 1990 as the followings; the construction Read More

A review focused on different methodologies applied as effective tools for the construction of β phosphapeptides starting from βamino phosphonic and phosphinic acid derivatives as building blocks is reported. βPhosphapeptides can be considered as mimetics of peptides derived from βamino acids, in which the carbon atom of carboxylic acid group is replaced by a phosphorus atom, and these compounds have attracted a part Read More

[1,3,5]-Triazine derivatives have traditionally found applications in analytical chemistry as complexation agents, in electrochemistry as multi-step redox systems and as pesticide or herbicide components in agriculture. In the last years, there has been a growing interest in these compounds that have been used, for example, as templates in multidimensional crystal engineering involving metal complexes for producing nanom Read More

A review of literature on the synthesis of 8-azasteroids is presented.
