Synthesis of 5-Diphenylphosphinoyl-2,3-dihydropyran-4-ones
摘要:
5-Diphenylphosphinoyl-2,3-dihydropyran-4-ones are readily prepared from the corresponding 5-diphenylphosphinoy-1-1-buten-3-yne under mild acidic conditions. The phosphorus substituted pyrones are converted to more substituted pyrones via 1,4-addition of copper reagents followed by Horner-Wittig reaction.
