Reaction Steps

A 500 ml round bottom flask was charged with 20.32 g (0.103 mol) of 3,3-dimethyl-1,5-dioxazpiro[5.5]undecan-9-one (also known as 1,4-cyclohexanedione mono-2,2-dimethyltrimethylene ketal, from Aldrich Chemical Company, Milwaukee, Wis.), 21.6 g (0.365 mol) of n-propylamine (Eastman Chemical Company, Rochester, N.Y.), 0.01 g of p-toluenesulfonic acid and 100 ml of toluene. The reaction mixture was refluxed for 24 hours with a water separator charged with 16 g of 3-A molecular sieves. The volatiles were removed in vacuo and the residue was held for further synthetic modifications as described below.
