    • 11. In related amino aryl diselenides, Wirth et al. have unequivocally established, by isolation, that an ethyl selenide (45% yield) is obtained upon treatment with diethylzinc. This ethyl selenide was proven not to be the dominant catalytically active species in the addition of diethylzinc to benzaldehycle (17% yield). Furthermore, these workers also provided NMR evidence for zinc sclenolate dimers: Wirth, T.; Kulicke, K. J.; Fragale, G. Helv. Chim. Acta 1996, 79, 1957-1966.

The term ami ami Re refers to the fact that in transition states 11a.b the bicyclo[2,2,0] core is anti to both the pyrrolidine ring and thiazazincolidine ring and that alkyl delivery is to the Re face of the aldehyde. In the case of the transition states 12a,b the description syn anti Si refers to the fact that the bicyclo[2,2,0] core is syn to the pyrrolidine ring and anti to the thiazazincolidine ring, alkyl delivery is to the Si face of the aldehyde.
