Iminium Salt

The effects upon enantioselectivity of substitution in the heterocyclic ring of biaryl iminium salt catalysts for alkene epoxidation are reported. The influence of dihedral angle in these systems has been investigated. Enantioselectivities of up to 97% ee were observed.

The binding of the trisaccharide (2-acetamido-2-deoxy-D-muramic acid)-β(1→4)-(2-aceta-mido-2-deoxy-D-glucosyl)-β(1→4)-(2-acetamido-2-deoxy-D-muramic acid) to subsites B, C, and D in lysozyme has been studied by 1H nuclear magnetic resonance methods. In particular, the coupling constant between H1 and H2 of the reducing saccharide bound in subsite D has been determined. The coupling constant for the bound saccharide indicates that the dihedral angle between C1 and C2 for the reducing saccharide is not significantly changed upon binding to lysozyme. This result is discussed in terms of other evidence for the role of distortion of the saccharide bound in subsite D in the lysozyme-catalyzed hydrolysis of cell wall oligosaccharides.

The article considers the large gas fields geology aspects of which are totally in conflict with the principles of anticline theory of hydrocarbon accumulation. These fields are situated in orogenic formations and associated with large synclinal structures. Any seals and lateral screens are absent. Gas saturated reservoirs are surrounded by relatively large-porous water-saturated sandstones and retained in pools due to the capillary forces. The nature of these fields is determined by the molecular physics laws, which effect in oil-wet porous media. These areas are abundant within the geosynclinal systems where synclinal structures can be considered as perspective for oil-and-gas content.
