Reaction Steps
To a solution of 4.25 g of 2-hydroxymethyl-6-methyl-3-(5-carboethoxypentyloxy)-4-pyrone in 110 ml of acetonitrile was added 12 g of activated manganese dioxide. The resulting suspension was stirred for 3 hr, at which time the mixture was filtered and the filtrate evaporated to an oil, 2-formyl-6-methyl-3-(5-carboethoxypentyloxy)-4-pyrone, weighing 4.0 g (94%). NMR (CDCl3): δ1.23 (3H, t, J=7 Hz), 2.36 (3H, s), 6.32 (1H, s).
