Literature References

Alternative reagent with enhanced stability for many of the reactions conventionally carried out using 3-Chloroperoxybenzoic acid, L00286. For a comparative study of the two reagents, see: Synthesis, 1015 (1987).


For regioselective epoxidation of allylic alcohols in water, see: J. Org. Chem., 57, 1198 (1992).


Cyclic ketones undergo the Baeyer-Villiger reaction to give lactones in high yield, in acetonitrile: Synth. Commun., 26, 4591 (1996), or in methanol-water in the presence of NaHCO3: J. Org. Chem., 62, 2633 (1997); the latter method has been used in the synthesis of massoia lactone.
