| titleOfInvention | Process for preparing azetidine derivatives and novel intermediates therein |
| abstract | Process for the preparation of a compound of formula or a salt thereofn wherein R, represents a hydrogen atom or a group of formula R 2 SO 2 or phenyl-CH(R3)-wherein R 2 represents a phenyl, tolyl or C 1-4 alkyl group and R 3 represents a hydrogen atom or a phenyl or C 1 . 4 alkyl group, which process comprises contacting nickel in an oxidation state of at least 3 with a 3-hydroxymethyl azetidine derivative of formulan wherein R 4 represents a group of formula R 2 SO 2 or phenyl-CH(R 3 )-and R 5 represents a hydrogen atom or a hydroxymethyl group or a group of formula COOH or a salt thereof, followed, where R 5 is not a hydrogen atom, by the decarboxylation of the compound of the 3,3-dicarboxylic intermediate product or a salt thereof and. if desired to produce a compound in which R. represents a hydrogen atom, by deprotection of the N-atom. Also. novel N-substituted azetidine carboxylate derivatives of the formulan wherein X represents a group CH 2 OH or COOY where Y represents a hydrogen or an alkali or alkaline earth metal atom. |
