Regioselectivity of rhodium(II)-catalyzed decomposition of 1-alkyl-1-(diazoacetyl)alkenes. Synthesis of 2-alkyl-2-cyclopentenones and 2-alkylidenecyclopentanones
摘要:
The synthesis of 1-alkyl-1-(diazoacetyl)alkenes and their dirhodium tetraacetate catalyzed transformation into 2-cyclopentenones and 2-alkylidenecyclopentanones are described. The competitive, intramolecular carbon-hydrogen insertion at two gamma-centers is discussed.
