Fortschritte der Chemie organischer Naturstoffe Progress in the Chemistry of Organic Natural Products Book Review:

In order to make further progress in elucidating the mechanism of NOS catalysis it will be essential to throw light on the interaction between the enzyme and its substrate. An understanding of the catalytic site will also assist the development of therapeutically important NOS inhibitors. In particular. it will be useful to uncover any differences that exist between the substrate binding sites of the three NOS isozymes which might be exploited for the development of isoform selective NOS inhibitors. A comparison of NOS to other Arg-binding proteins has shown no significant sequence homology (159). Moreover, the lack of a 3D structure and absence of significant sequence homology between the NOS oxygenase domain and known cytochromes P450 has made it difficult to identify residues and construct a model of the distal heme pocket responsible for substrate binding. However, a number of groups are currently working towards crystallisation of the separate NOS reductase and oxygenase domains of the three isoforms for X-ray diffraction studies; the first X-ray structure is likely to be forthcoming within a matter of months. * The results of these studies are expected to resolve many of the uncertainties surrounding the structure of the NOS catalytic site. Preliminary X-ray diffraction analysis of CPR from rat liver has already been reported by MASTERS et al. (524) and the future emergence of a detailed structure for this protein should throw light on the structure and function of the NOS reductase domain.

Handbook of Surfactants Book Review:

The worldwide consumption of surfactants now exceeds several million tonnes per annum. Six ofthe major types represent approximately 80% ofthe volume consumed, whereas the remaining 20% is made up of approximately 40 different chemical types. Commercially produced surface active agents are not pure chemicals, and within each chemical type there can be tremendous variation. Technical staff who are not familiar with surfactants are frequently bewildered by the enormous variety of different products on the market and the vast body of literature which exists on the composition and properties of surfactants. The selection of the best surfactant for any given use therefore becomes a major problem. This volume arose from the clear need to have available a simple reference book summarising the different types of surfactants on the market and their properties. The concept and structure of the book evolved from early attempts to define chemical structure/property relationships of all the different types of surfactants commercially available, into a simple handbook providing essential background information for the surfactant user. It is realised that most users will be developing their own data bank of structure/end use property relationships and they will therefore be the experts on end use.

A Modular and Concise Total Synthesis of daurichromenic Acid and Analogues And A New Method for the Mild and Selective Mono dealkylation of Tertiary Amines microform Book Review:

This thesis consists of two parts. Part One concerns the total synthesis of (±)-daurichromenic acid and a series of structural analogues. Daurichromenic acid, a natural product isolated from the leaves and twigs of Rhododendron dauricum, has potent anti-HIV activity. A concise synthetic route was designed whereby the target module was prepared in four steps from trans,trans-farnesal, ethyl crotonate and ethyl acetoacetate. Furthermore, the modular nature of the synthetic route allowed for the preparation of a variety of structural analogues of the natural produce. Although the overall yield of this route was relatively low, significant quantities of analytically pure materials have been obtained for subsequent biological evaluation. Two alternative routes were explored in order to circumvent a problematic dehydrogenation/aromatization step encountered in this route. In these instances, attempts were made to install the aromatic ring of the target compound through micration of a carbon-carbon dougle bond and via a retro-Diels-Alder reaction. Moreover, a strategy employing a phenylboronic acid-promoted condensation reaction of methyol orsellinate and +, -unsaturated aldehydes as the key step was also developed. This provided additional access to a series of structural analogues of (±)-daurichromenic acid from commercially available starting materials. In Part Two of the thesis a new procedure for the mono-dealkylation of tertiary amines is described. Attempted oxidation of a known hydroxy crown ether derivative, 2,3,9,10-dibenzo-6-hydroxy=16-crown-5, under modified Swern conditions resulted in the unexpected formation of a diethylamide as the major reaction product. Based on this initial observation, a novel and facile means was developed for the mono-dealkylation of a series of tertiary amines using a monoester of oxalyl chloride as the cleaving agent. The experiments also demonstrated that various alkyl groups could be cleaved and the selectivity of the bond breaking process was: benzy>ally1>methyl>hetrocyclic ring. The chemoselectivity of this new dealkylation procedure was demonstrated by performing the selective removal of the N-benzyl group of (2S)-1-benzyl-2-[(benzyloxy)methyl]pyrrolidine. The reaction proceeded cleanly and resulted in the isolation of the desired amide product in 83% yield. Subsequent hydrolysis of the amide product afforded (2S)-2[(benzyloxy)methyl]pyrrolidine in excellent yield.
