- Preparation of 3-(n-alkenoxy)propanoic acids
-
3-(n-Alkenoxy)propanoic acids have been prepared by reaction of alkenols with tert-butyl acrylate (catalyzed by Triton B or n-butyl lithium) followed by cleavage of the tert-butyl group by CF3COOH or KO2.

- Organoselenium and DMAP co-catalysis: Regioselective synthesis of medium-sized halolactones and bromooxepanes from unactivated alkenes
-
A catalytic system consisting of bis(4-methoxyphenyl)selenide and 4-(dimethylamino)pyridine (DMAP) has been developed for the regioselective synthesis of medium-sized bromo/iodo lactones and bromooxepanes possessing high transannular strain. 77Se NMR, mass spectrometry and theoretical studies reveal that the reaction proceeds via a quaternary selenium intermediate.

- Oxidative cyclization of alkenoic acids promoted by AgOAc
-
Alkenoic acids derived from salicylic acid and analogues undergo an unexpected oxidative cyclization process triggered by AgOAc leading to 4H-benzo[d][1,3]dioxin-4-ones. The process is affected by the substitution on the aryl and the allyl units.
