Abstract
A new three-step synthesis in good overall yield of 1,4-ketoaldehydes and 1,4-diketones is described. The method involves two sequential coupling reactions of Grignard reagents with S-phenyl carbonochloridothioate in the presence of nickel(II) or iron(III) complexes as catalysts. Application of this reaction to the synthesis of Z-jasmone and dihydrojasmone is also described.
