Hydroboration of 1,1′-bi(cyclopent-1-ene) and 3,3′-biindene: Experimental and theoretical study

Hydroboration of bi(cyclopent-1-ene) (1) or 3,3′-biindene (2) with borane, thexylborane or (-)-isopinocampheylborane afforded, regardless of reaction conditions, meso-isomers of polycyclic 1,4-diols 3a, 4a as the main products. No reaction was observed with 9-BBN. The structure of the major product 4a, as well as of the minor racemic product 4b was assigned based on 1H NMR spectra of the corresponding Mosher's diesters 5a-5c. Finally, the stereochemistry of the product 4a was confirmed by a single-crystal X-ray analysis of the corresponding dimesylate 6. To elucidate preferential formation of the weso-isomers, complexes of monohydroborated intermediate with borane were studied theoretically by DFT methods.

Renewable high-density spiro-fuels from lignocellulose-derived cyclic ketones

Renewable high-density spiro-fuels are synthesized from lignocellulose-derived cyclic ketones for the first time, which show higher density, higher neat heat of combustion and lower freezing point compared with other biofuels synthesized from the same feedstock, and thus represent a new type of renewable high-density fuel attractive for practical applications.

Total synthesis of the originally assigned structure of vannusal B

(Chemical Equation Presented) The truth is out there: The chase for the originally assigned structure of vannusal B (see structural formula) by total synthesis ended successfully, but created a new puzzle, that of the true structure of this intriguing marine natural product.
