Appendix 1. Diels-Alder Reactions

One of the most efficient methods (high yield, controlled stereochemistry, diverse functionality) to construct rings from smaller fragments is via cycloaddition reactions. The reverse reaction, namely splitting of a ring into smaller fragments is termed a cycloreversion reaction is also an important synthetic tool. (For example, in the present experiment it is the cracking of cyclopentadiene di...

Silviculture in Red Alder Stands

In the past, there has been an emphasis on conifer tree species in forestry operations in British Columbia. As a result, there is a serious lack of information regarding disease and decay problems in most hardwood tree species. This presentation reports the results of recent studies on levels of decay in natural red alder stands, and on the formation of stain in harvested alder logs. Disease pr...

Diels–Alder reactions in water*

This review illustrates how water, as an environmentally friendly solvent, can have significant additional benefits when it is used as a solvent for the Diels–Alder reaction. The mechanism by which the unique properties of water enhance the rate and selectivity are discussed. Also, possibilities for the achievement of further increases in rate and enantioselectivity of aqueous Diels–Alder react...
