Abstract
The first example of the preparation of α-diazo-β-hydroxy esters by the aldol-type condensation of aldehydes with ethyl diazoacetate using Et3N as base in the presence of magnesium iodide etherate [MgI2.(Et2O) n ] has been achieved in good to excellent yields at room temperature in CH2Cl2 in 15–30 min.
