Cross Metathesis with Strained Exocyclic Enones: Synthesis of 3-Alkylideneoxetan-2-ones from 3-Methyleneoxetan-2-ones
摘要:
3-Alkylideneoxetan-2-ones have been prepared in good to excellent yields with high Z-selectivity by olefin cross metathesis with 3-methyleneoxetan-2-ones in the presence of second generation metathesis catalysts 1 or 2.
