Title: Reactions of silyl enol ethers and ketene silyl ketals with isocyanates
Abstract: The reaction of silyl enol ethers with aryl isocyanates gave 2-siloxycycloalk-1-enecarboxamides or 4-siloxyazetidin-2-ones, depending on the structure of silyl enol ethers. On the other hand, ketene silyl ketals reacted with isocyanates to afford 2-(N-silylcarbamoyl)alkanoates or 4-siloxy-4-alkoxyazetidin-2-ones dependent upon the structure of isocyanates. These adducts were easily desilylated to the corresponding 2-carbamoylalkanones or 2-carbamoylalkanoates.
