General Method

A new electrochemical methodology has been developed for the preparation of a wide variety of functionalised orthoesters under mild and green conditions from easily accessible dithiane derivatives. The new methodology also offers an unprecedented way to access tri(fluorinated) orthoesters, a class of compound that has never been studied before. This provides the community with a rapid and general method to prepare libraries of functionalised orthoesters from simple and readily available starting materials.

General Method

Various branched-chain carboxylic acids have been oxidized with the following reagents: (A) potassium manganate in dilute alkali; (B) potassium permanganate in concentrated alkali; (C) potassium peroxydisulphate in dilute alkali; (D) potassium peroxydisulphate in dilute acid. In most cases hydroxy-acids were formed by oxidation at the tertiary position but the yields were poor. None of these reagents appears to provide a general method for the preparation of lactones from branched-chain saturated carboxylic acids.

General Method

5-Arylpyrrole-2-carboxylic acids are important key intermediates in the synthesis of HIV-1 entry inhibitors (such as NBD-11021 and NBD-14010). Here we present a general method for the synthesis of some 5-arylpyrrole-2-carboxylic acids in three steps starting from pyrrole. By this method, the compounds could be prepared on gram scale and without chromatographic purification.
