Cyclic derivatives of Baylis–Hillmanadducts were synthesized. Cobalt-catalyzed peroxidation of these cyclic lactones afforded silyl peroxides in diastereomeric ratios ranging from 91:9 to 97:3.

The thermally induced Arbuzov rearrangement of allyl diethyl phosphites gives, under unprecedented mild conditions, a variety of diethyl allylphosphonates with high stereoselectivity and in high yield.
Intramolecular hydrogen bonding facilitates nucleophilic addition of sulfones to Baylis-Hillman adducts in a single step to realize the substituted allyl sulfones. The reaction is performed in PEG (400 MW) as solvent, which allows easy solvent recycling. (c) 2006 Elsevier Ltd. All rights reserved.
