First iodine-catalyzed deallylation of reactive allyl methylene esters

C-Allyl cleavage has been developed using the inexpensive and mild reagent iodine in dimethylsulfoxide. A variety of compounds with active methylene groups were C-deallylated using this reagent. This method is efficient and operationally simple in comparison to the methods using transition-metal complexes. Supplemental materials are available for this article.

Studies in the Friedel-Crafts reaction: Part VI - Synthesis and intra-, and intermolecular Friedel-Crafts reaction of 2-methyl-4-phenylpentanedioic anhydride

2-Methyl-4-phenylpentanedioic acid 4 is prepared by the Michael reaction of methyl methacrylate with ethyl/methyl phenylacetate or benzyl cyanide followed by the hydrolysis of the adduct. The reaction has been studied using different bases. 4 is converted
