Conformations of Alkanes and Cycloalkanes
Hydrogen peroxide is formed in the cells of plants and animals but is toxic to them. Consequently, living systems have developed mechanisms to rid themselves of hydrogen peroxide, usually by enzyme-catalyzed reduction to water. An understanding of how reactions take place, be they reactions in living systems or reactions in test tubes, begins with a thorough knowledge of the structure of the re...

Preview You learned in the Chapter 1 that all organic molecules have carbon skeletons. These carbon skeletons show great diversity in the ways that C atoms bond to each other, and in their three-dimensional shapes. Alkanes and cycloalkanes consist entirely of carbon skeletons bonded to H atoms since they have no functional groups. As a result, they serve as a basis for understanding the structu...
متن کاملHighly enantioselective hydroamination to six-membered rings by heterobimetallic catalysts.
New bimetallic Zn/Zr salen-type systems were employed as catalysts in the asymmetric intramolecular hydroamination reaction. High enantioselectivity for the formation of piperidines of up to 98% ee were observed.

similar procedure and the same type of interaction model were used for glucose solutions. Specifically, MD simulation was carried out using the DL_POLY2.0 package. The MD trajectories were generated using the SPC/E potential model for water and the optimized potential for liquid simulation (OPLS) all-atom force field for carbohydrates, developed by Jorgensen and co-workers, for both trehalose a...
متن کاملPalladium-catalyzed carbocyclization of 1,6-enynes leading to six-membered rings or oxidized five-membered trifluoroacetates.
We describe palladium-catalyzed carbocyclization of 1,6-enynes leading to six-membered rings by water-originated hydride addition. Mechanistic features of this anomalous carbocyclization and isolation of a chiral five-membered C-Pd intermediate as an oxidized form of trifluoroacetate are also reported.
