An oxazolinyl ferrocenyl diselenide was synthesised by directed ortho-metal
ation and used as catalyst precursor in the asymmetric addition of diethyl-
and diphenylzinc to various aldehydes, yielding synthetically useful secon
dary alcohols, of which some are difficult to access using other catalytic
methodologies. Enantioselectivities of up to 44% for the former and up to 8
5% for the latter transformations were obtained.
