Reaction Steps
To a suspension of paraformaldehyde (3.4 g) in diisopropylphosponate (25 g) was added triethylamine (2 mL). The reactants were heated in a 130° oil bath with vigorous stirring for 4 h. The volatiles were removed on a rotavap and the residue was chromatographed on silica gel using ethyl acetate to afford 19.3 g of material. 1H NMR(DMSO-d6) δ 1.23 (d, 12H), 3.62 (dd, 2H), 4.59 (m, 2H), 5.31 (m, 1H)
