Intramolecular arene trapping of pyran-4-one derived zwitterions: a two-step synthesis of tetrahydrobenz[e]inden-1-ones
摘要:
Pyran-4-ones bearing pendant arene traps undergo efficient photolytic conversion to transient oxyallyl zwitterions, which then cyclize onto the arene in an intramolecular electrophilic aromatic substitution to yield tetrahydrobenz[e]indenones.
