“…Furthermore, reduction of 4 with NaBH 4 in MeOH provided a 3/1 mixture of meso/(()-1 alcohols in 99% yield. Concentration-sensitive dehydration 18 in the presence of no more than 1% p-TSA yielded one C 2 -symmetric isomer 5. This prochiral alkene can be transformed into the bisepoxide 3 using the low-temperature Jacobsen epoxidation conditions.…”

[Structure: see text]. The absolute configurations of three compounds with a rigid 1,8-disubstituted as-hydrindacene skeleton have been determined using vibrational circular dichroism spectroscopy and quantum chemical calculations. Experimental spectra were compared to B3LYP/6-31G and B3LYP/cc-pVTZ level predicted spectra. Based on the agreement between the predicted and experimental spectra, the stereochemistry could be assigned with high confidence. The results were found to be in agreement with ECD determinations and/or predictions based on the applied asymmetric methods in the synthetic route.

“…Thus, high selectivity to alkene was achieved for these alcohols. It is interesting to point out that a similar result is not feasible when H 2 SO 4 [19] or p-toluenesulfonic acid [27] are used as catalysts, since mainly cyclodimerization products are obtained.…”

Influence of the Alcohol Molecular Size in the Dehydration Reaction Catalyzed by Carbon-Supported Heteropolyacids

The catalytic performance of tungstophosphoric and molybdophosphoric acids supported on two commercial carbons, for dehydration reactions of several alcohols, was studied. The alcohol conversion depended on their molecular size, while selectivity to alkenes was also related to cyclodimer molecular size formed by certain alkenes in acidic medium. Acidity and mean pore diameter of the catalysts showed an influence on the conversion degree of the alcohols into alkenes and also into alkene cyclodimerization.
