4-hydroxy-2-butynal or acetylene dicarboxaldehyde, and the resulting stable dichloromethane solutions containing the chemically sensitive acetylene aldehydes were used directly in subsequent Wittig, Grignard, or Diels–Alder reactions. This method provides safe and efficient access to propynals and allows the preparation of polyfunctional acetylene compounds from readily accessible starting material without the
丙炔醇衍生物很容易用 Bobbitt 盐氧化,生成相应的丙炔醛产品。2-Butyn-1,4-diol 可以被选择性氧化以提供 4-hydroxy-2-butynal 或 acetylene dicarboxaldehyde,所得稳定的二氯甲烷溶液含有化学敏感的乙炔醛,可直接用于随后的 Wittig、Grignard 或 Diels –桤木反应。该方法提供了安全有效地获取丙炔醛的方法,并允许在不使用保护基的情况下从易于获取的起始材料制备多官能乙炔化合物。
