Electrochemical transformations of DDT into oxygen-incorporated products, amides and esters, catalyzed by a B12 derivative, heptamethyl cobyrinate perchlorate, have been developed under aerobic conditions. The dechlorinative oxygenation of DDT forms the acyl chloride as an intermediate for the synthesis of the amide and ester in the reaction with the amine and alcohol, respectively. This electrochemical method demonstrated with 20 oxygen-incorporated dechlorinated products up to 88% yields with 15 new compounds and was also successfully applied to the conversion of methoxychlor to an amide and ester.

By using a combination of a chiral N-triflyl phosphoramide and TiCl4 as the catalyst, a new process for asymmetric intramolecular hydroalkoxylation of unactivated alkenes was developed, producing various chiral tetrahydrofuran derivatives in 51%—99% yields with 30%—71% ee's.
Synthesis of nine-membered azlactones by palladium-catalyzed ring-expansion of γ-methylidene-δ-valerolactones with aziridines
Shintani, Ryo,Ikehata, Keiichi,Hayashi, Tamio
experimental part, p. 4776 - 4780 (2011/07/08)
A palladium-catalyzed formal [6 + 3] cyclization of γ-methylidene- δ-valerolactones with aziridines has been developed to produce 1,4-oxazonan-9-ones, a class of nine-membered azlactones that are not easily accessible by existing methods. The products thus obtained can also be further functionalized with ease.
