- Masked ß-formylethyl synthon, compare preceding entry. The derived Grignard, which, unlike the dioxane analogue, is unstable above room temperature, shows similar attenuated reactivity in comparison with simple alkyl Grignard reagents, reacting with acid chlorides to give -ketoaldehydes without carbinol formation, and with enones to give, at low temperatures, predominantly the 1,4-addition product without the need for Cu catalysis:Tetrahedron Lett., 28, 3217 (1987).
