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.
描述了一种新的三步合成法,其合成了1,4-酮醛和1,4-二酮的良好总收率。该方法包括在镍(II)或铁(III)配合物作为催化剂存在下,格氏试剂与S-苯基碳酰氯硫代酸酯的两个顺序偶联反应。还描述了该反应在Z-茉莉酮和二氢茉莉酮的合成中的应用。
