note
-
We have been unable to determine with complete certainty the relative or absolute stereochemistry of the compounds in this Letter, but from the known conformational preference of related ureas (see Ref. 20) we deduce syn stereochemistry for the more thermodynamically stable of each pair of sulfoxides. The major product of m-CPBA oxidation turns out also to be the more stable, where both were determined. Absolute stereochemistry is deduced from the fact that (S)-13 gives (S) sulfoxides (Ref. 17i), and if the syn (=M, S) sulfoxide is formed faster the remaining sulfanylurea should be P.
