Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: (3S,4S)-4-[(2R)-3-Oxotetrahydropyran-2-yl]-1-(trimethylsilyl) -3-[(R)-1-(trimethylsilyloxy)ethyl]azetidin-2-one was reacted as in Reference Example 38 except that 1,2-bis(allyloxycarbonyl)-4-phenylsulfonylthiopyrazolidine was used in lieu of S-methyl benzenethiosulfonate to give (3S,4S)-4-[(2R)-4-[[1,2-bis(allyloxycarbonyl)pyrazolidin-4-yl]thio]-3-oxotetrahydropyran-2-yl]-3-[(R)-1-(trimethylsilyloxy)ethyl]azetidin-2-one.
