• (Sa,R,R)-9 has also been similarly studied. In this case, the matched combination was determined in previous works that investigated the scope of enantioselective silver(I)-catalyzed 1,3-DC of azomethine ylides and dipolarophiles [25][29]. The enantioselectivities were moderate, even when using AgSbF6
