Scheme I. The N-(substituted-phenylsulfonyl)-N-phenylglycines can be obtained directly by reaction of 8 with N-phenylglycine 9 in aqueous THF containing 2 equiv of base. Alternatively, the N-(phenylsulfonyl)-N-(sub-stituted-pheny1) glycines were prepared in a multistep sequence via the intermediate sulfonamides ll (Scheme I). Reaction of 8 with anilines 10 in dichloromethane using triethylamine base provided the intermediate ...
