Anthracenic and naphthalenic vic-diepoxides. A new kind of isomerization going through fragmentation
摘要:
When treated with Lewis acids in an anhydrous medium, syn and anti anthracenic and naphthalenic vic-diepoxides 2 and 3 rearrange more or less completely to acyl-benzo, or naphthopyrans 1. This rearrangement, competing with more classical ones, appears to involve a Grob-type fragmentation followed by recyclisation. (C) 1997 Elsevier Science Ltd.
