Abstract
Summary: Silyl enol ethers and silyl ketene acetals react with sulfenamides in the presence of trimethylsilyl triflate to give the corresponding trans-sulfenylated ketones and lactones. ... We have recently demonstrated the utility of the 2- phenylthio group for controlling the stereoselectivity of nitrogen glycosylation reactions used in the synthesis of the anti-HIV nucleoside, D4T (3, Scheme I).l In order for this overall approach to be successful, we required a reagent that would ...
