C. Jimeno et al., A purely synthetic, diversity amenable version of norephedrine thiols for the highly enantioselective diethylzinc addition to aldehydes, SYNLETT, (7), 2001, pp. 1155-1157
A new beta -aminothiol arising from purely synthetic yet enantiopure aminoa
lcohols has bern prepared and successfully used in the addition of diethylz
inc to aromatic aldehydes, yielding secondary alcohols in ee's up to 99%.
