Cyclization of γ-amino-α-bromocarboxylic esters resulted in an efficient synthesis of new 3,3-dimethoxyazetidine-2-carboxylates, that is, methyl N-t-butyl-3,3-dimethoxyazetidine-2-carboxylic ester and 3,3-dimethoxyazetidine-2-carboxylic acid, or 3-bromo-4

A process for the production of 4-chloro-3-alkoxy-but-2E-enoic acid alkyl esters starting from 4-chloroacetoacetic acid chloride by reaction with a dialkyl sulfite. The produced intermediate products are used as structural elements for, i.a., pharmaceutical agents.
