A convenient synthesis of protected e-enynals via cross coupling of vinyltin acetals with bromoalkynes
摘要:
E-conjugated enynes bearing an acetal function on the allylic or the homoallylic position or/and on the propargylic or the homopropargylic position were conveniently obtained at room temperature in DMF via cross coupling of the corresponding vinyltins with 1-bromoalk-1-ynes in the or Pd(II) catalysts.
