Synthesis and acid-promoted ring opening of a novel cage spiro-oxetane
摘要:
When heated with glacial HOAc and concentrated H2SO4 (catalytic amount), cage oxetane 1 undergoes ring opening with concomitant skeletal rearrangement, thereby affording a mixture of bis(acetoxy)trishomocubanes, 7a and 8a (ratio 4:1).
