2-Methyl-1,6-dioxaspiro[4.4]nonane-2-carbaldehyde → (2-Methyl-1,6-dioxaspiro[4.4]nonan-2-yl)methanol

Participants

Reaction Steps

A solution of 1.70 g of 2-methyl-1,6-dioxaspiro[4.4]nonane-2-carboxaldehyde in tetrahydrofuran was hydrogenated at 60 p.s.i. and 20° C. for 5 hours in the presence of 1.0 g triethylamine promoter and Raney nickel, that had been rinsed in tetrahydrofuran. When all of the starting material had disappeared, the mixture was treated with magnesium sulfate and filtered. Distillation of the filtrate gave 1.43 g of the desired product as a colorless liquid, b.p. 65°-70° C. (1 torr.).
