α-Diazo-β-hydroxyketones, obtained by condensation of aldehydes with 1-diazo-1-lithioacetone, are efficiently transformed into the corresponding β-diketones by exposure to rhodium(II) acetate. The sequence is applied to a new synthesis of β-damascone (10).
通过将醛与1-重氮-1-
硫代丙酮缩合而制得的α-重氮-β-羟基酮可通过暴露于
乙酸铑(II)而有效地转化为相应的
β-二酮。该序列被应用于新合成的β-
金刚烷酮(10)。
