Pinacol-type rearrangements of intramolecular photocycloadducts: Application of the 2,2-dimethyl-4-pentenoate protecting group
摘要:
A pinacol-type rearrangement of intramolecular photocycloadducts has been accomplished by exploiting a novel ester protecting group that can be easily removed from a hindered alcohol. The ester is removed by an intramolecular lactonization, overcoming the steric factors normally associated with pivalate esters. (C) 1998 Elsevier Science Ltd. All rights reserved.
