The Endocyclic Restriction Test: Oxygen Transfer from N-Sulfonyl Oxaziridines to Alkenes
摘要:
[GRAPHICS]The transition state for the transfer of oxygen from N-sulfonyl oxaziridines to alkenes has been investigated experimentally using the endocyclic restriction test. Molecules containing oxaziridines and alkenes were prepared and the ability of each system to intramolecularly transfer oxygen was evaluated, The results are consistent with a transition state in which N-O bond cleavage is more advanced than C-O bond cleavage.
