Ahn and coworkers developed stilbenediamine-derived 1,2,5-thiadiazoli-dine-1,1-dioxide-based chiral auxiliary 140 and demonstrated its utility in syn aldol reactions [49]. Excellent selectivity and yield were observed for a variety of aldehydes, as shown in Table 2.24, entries 1-3. The cyclic sulfa-mide auxiliary is novel in that it is bifunctional and C2-symmetric, so only... 

Headley and coworkers developed suJfamides St9a [109], 99b [110], and 100 (Figure 22.8) [111] bearing the (S)-pyrrolidine and 1,3-dialkylimidazolium structural units, which exhibited a high catalytic performance in asymmetric Michael additions of enolizable aldehydes or ketones to P-nitrostyrene derivatives. Sulfa-mide 100 [111] and ClL-catalyst 101 synthesized by Xu and coworkers [112], in...
