experimental part, p. 6423 - 6429 (2011/02/24)
The aza-Michael addition of secondary amines to α, β or ββdisubstituted α, βunsaturated esters was efficiently achieved under high pressure (10-16 kbar) in protic solvents in the absence of any catalyst. The expected cumbersome β-aminoesters bearing a tertiary amine directly connected to a quaternary carbon atom could be isolated in fair to good yields. By using αβδγ-unsaturated esters (alkyl sorbate), the addition took place regioselectively in a 1,6 manner and afforded the β,γ -unsaturated δ-aminoesters. Copyright
Solvolytic Hydroperoxide Rearrangements. 2. Oxa Bicyclic Hemiketal Peroxides from Homoallylic and Cyclopropylcarbinyl Precursors

Studies in this laboratory have resulted in the discovery of a novel hydrogen peroxide mediated ring expansion that is suitable for the synthesis of medium to large ring oxa bicyclic compounds.This rearrangement involves the solvolysis of homoallylic bros
