PROBLEM 22.20 The Koenigs-Knorr reaction is useful for making glycosides. In this reaction, the pentaacetate compound of Figure 22.37 is treated with HBr to give the C(l) bromide.The bromide is then replaced by an alcohol in the presence of AgaO.The reaction is very selective for the P anomer, but a series of experiments has established that it is not a simple Sn2 reaction. Show a mechanism that explains the selective formation of the P anomer. Hint Remember Chapter 21. [Pg.1149]
