Publikováno v: Tetrahedron: Asymmetry. 10:3253-3257

Diastereomeric ferrocenic amino-alcohols combining three elements of chirality (one of which is a ferrocenic plane) are tested as catalysts in the alkylation of benzaldehyde with diethylzinc. Good to excellent yields and ees were obtained and show co
