    • note
    • The microwave-assisted (200 W) silver-catalyzed imination of methyl phenyl sulfoxide (1a) led to sulfoximine 2 in 85% yield (unoptimized) after 20 min, and it occurred in a sterospecific manner.

    • Cleavage of the SES-group by treatment with TBAF is also well-established (compare ref 7c), and there is no indication that this protocol leads to racemization.
