T. Ooi et al., A convergent, homochiral bis(amino alcohol) for obtaining high enantioselectivity in the addition of diethylzinc to aldehydes, CHEM LETT, (11), 2001, pp. 1108-1109
A new bimetallic approach using dibenzofuran derivative as a requisite spac
er has been introduced to achieve high asymmetric induction in the addition
of diethylzinc: to aldehydes with otherwise ineffective amino alcohol resi
due.
