A convenient method for the stereoselective synthesis of cis-α,β-epoxyesters and aldehydes is established according to the Sn(OTf)2 mediated cross aldol reaction between α-bromo-α′-silyloxyketone and aldehyde. The reaction is applied to the stereoselective synthesis of 2-amino-2-deoxy-d-arabinitol.
