successfully converted to α-oxy-α′-diazo ketone in three steps. The photochemical reaction of this new diazo compound provides an improved synthesis of the 3-hydroxy-2-methyl carboxylate derivative 2 in threo relative configurations via a Wolffrearrangement. The influence of the protective group on the stereochemical result of the photochemical reaction is discussed.

different stabilized diazocompounds is reported. Studies on the reactivity of the condensation products have been undertaken, finding out novel transfromations of β-oxy-α-diazo carbonyl compounds with sinthetic applications. Thus, a stereoselective Wolff rearrangement provided syn 2-hydroxy-1-methyl compounds, which represent macrolide type structural subunits. On the other hand, rhodium (II) mediated rearrangements
