Omega-alkoxy derivatives of lactams

Abstract

Abstract Compounds of the formula ##STR1## in which R 4 represents an alkyl radical having from 1 to 4 carbon atoms, R 5 represents a linear or branched alkylene radical having from 1 to 10 carbon atoms in the chain which may be substituted by groups which are not reactive under the applied conditions, and R 6 represents hydrogen or a branched alkyl radical having from 3 to 10 carbon atoms with a secondary or tertiary N-α-C atom, are prepared by anodic alkoxylation of lactams of the formula ##STR2## with an alcohol of the formula R 4 OH, in which formulae R 4 , R 5 and R 6 have the aforesaid meaning, in the presence of at least one alkali metal or tetraalkylammonium tetrafluoroborate, hexafluoroborate or nitrate as conducting salt, at a temperature of up to about 100° C in an electrolytic cell with stationary or flowing electrolyte. Some of the products are novel. They can be used as intermediates for the manufacture of pharmaceuticals, as antistatic agents in textile materials, and for the preparation of flotation agents, sex attractants for insects, α-amino-α, ω-dicarboxylic acids, α, ω-diaminocarboxylic acids, etc.
