A preparative method was developed for the synthesis of 2-isopropyltetrahydropyran-4-one, which was then transformed by the action of ethyl cyanoacetate into ethyl (2-isopropyl-4-tetrahydro-pyranylidene)cyanoacetate. Reaction of the latter with o-methoxyphenylmagnesium bromide followed by saponification and reduction with LiAlH4 led to 4-(2-aminoethyl)-2-isopropyl-4-(o-methoxy-phenyl)tetrahydropyran. A series of new azomethines, which are reduced to the corresponding amines by the action of NaBH4, were synthesized by the reaction of the above-mentioned amine with aromatic aldehydes.
