Hydride Reduction

A series of 3-indolylalkylaminoalcohols have been obtained from the lithium aluminum hydride reduction of the amides prepared by the reaction of 3-indoleglyoxylyl chloride and 2-methyl-3-indoleglyoxylyl chloride with primary aminoalcohols. When acetone was used as solvent in the reaction of 3-indoleglyoxylyis chloride and either 2-aminoethanol or 3-aminopropanol, the solvent participated in the reaction resulting in the formation of 2,2-dimethyl-3-(3-indoleglyoxyl)oxazolidine and 2,2-dimethyl-3-(3-indoleglyoxyl)tetrahydro-1,3-oxazine respectively. When the latter two compounds were reduced by lithium aluminum hydride, both carbonyl groups were completely reduced and reductive cleavage of the oxazolidine and tetrahydro-1,3-oxazine rings occurred to form the corresponding open-chain alcohols.
