A protocol for the hydrocarboxylation of disubstituted alkenes and terminal alkynes providing access to different secondary carboxylic acids and malonic acid derivatives has been developed. This methodology relies on an initial hydroboration using 9-BBN followed by carboxylation with carbon dioxide in the presence of a copper catalyst and the additive, cesium fluoride. Different cyclohexene, styrene, and stilbene derivatives could be utilized, and alkynes could be transformed into their corresponding dicarboxylic acids in good yields. Finally, six different terpenoids were carboxylated using the developed procedure. (Chemical Equation Presented).

The synthesis of the previously reported thianinhydrin (12) was achieved from 3-methylthiophene via the corresponding 5,6-dihydrocyclopenta[b]thiophen-4,6-dione (10). Conversion of 10 to the tricarbonyl (12) proceeded in good yield using dimethydioxirane oxidation of 5,6-dihydro-5-dimethyl aminomethylenecyclopenta[b]thiophen-4,6-dione (14). The fluorescence intensity of the zinc salt of the product of 12 and glycine was similar to that obtained from the product of ninhydrin and the same amino acid.

Chiral poly(thiophenes) obtained from two enantiomerically pure monomers can stereoselectively recognize anions used as doping agents during voltammetric cycles.

, p. 658 - 661 (2007/10/02)
Chiral poly(thiophenes) have been synthesized by electropolymerisation: they exhibit high specific rotation, stability, and conductivity and can stereoselectively recognize chiral anions used as doping agents during voltammetric cycles.
