A Novel Method for the Alkoxylation of Azetidin-2-ones at the 4-Position
4-Sulfinylazetidin-2-ones were reacted with various types of tributyltin alkoxides in the presence of a catalytic amount of trimethylsilyltrifluoromethanesulfonate to give the corresponding trans-alkoxyazetidin-2-ones in high yields.
