METHOD FOR PREPARING COMPOUNDS DERIVED FROM THIAZOLIDINEDIONE, OXAZOLIDINEDIONE

摘要

The invention relates to method for preparing a compound derived from thiazolidinedione, oxazolidinedione or hydantoin having formula (I) from a compound having formula (II) as follows: wherein Q represents an oxygen atom, a sulphur atom, Q1 represents an oxygen atom or a sulphur atom, R1 and R2, which can be identical or different, represent a hydrogen atom, a C1-10 alkyl chain; a cycloalkyl, an alkylaryl, arylalkyl; said alkyl, cycloakyl, alkylaryl or arylalkyl groups being optionally substituted by an alkyl, an alkoxy or aryloxy, a halogen, a hydroxy, a sulfino, a sulfonyl, an amino such as NH2, NHR3, N(R3)2, with R3 representing an alkyl, an alkoxy or an alkylcarbonyl. The inventive method is characterised in that a compound having formula (II) is made to react with the formic acid in the presence of a transition metal-based catalyst in order to produce the corresponding formula (I) compound.
