This kind of chemical reactivity of epoxides is rather general Nucleophiles other than Gng nard reagents react with epoxides and epoxides more elaborate than ethylene oxide may be used All these features of epoxide chemistry will be discussed m Sections 16 11-16 13... 

Before examining the more recent developments involving single-site metal catalysts for the copolymerization of C02 and epoxides, it may be worthwhile discussing some general features of these processes, and also defining some commonly used terms. First of all, the reaction sequences depicted in Scheme 8.1 are not... 

The essential features of the Masamune-Sharpless hexose synthesis strategy are outlined in a general way in Scheme 4. The strategy is based on the reiterative- application of a two-carbon extension cycle. One cycle comprises the following four key transformations (I) homologation of an aldehyde to an allylic alcohol (II) Sharpless asymmetric epoxidation of the allylic alcohol ... 

This is a general method of preparing hexaalkylphosphorous triamides from the corresponding dialkylamines. The procedure is simple, and the yields are high. Hexaalkylphosphorous triamides are powerful nucleophiles.8 This feature can be used in a rather unique way to synthesize epoxides directly from aldehydes.8, 6... 

General features—Reactions of alcohols, ethers, and epoxides... 

We begin our discussion of the chemical reactions of alcohols, ethers, and epoxides with a look at the general reactive features of each functional group.
