Benzene dioxygenase (BDO; EC 1.14.12.3) from Pseudomonas putida ML2 dihydroxylates benzene to produce cis-1,2-dihydroxy-cyclohexa-3,5-diene. As well as oxidising benzene and toluene, cell-free extracts of Escherichia coli JM109 expressing recombinant BDO oxidised cyclohexene, 1-methylcyclohexene and 3-methylcyclohexene. In an attempt to construct
The relative energies of cyclohexane-1,2-diols and chiral tetrapeptide (2 (Boc) or 3 (Moc)) complexes calculated using DFT indicate a thermodynamic preference for chiral recognition toward (1R,2R)(e,e)-alpha isomer. The barrier for stereoselective acyl transfer is identified as lower for trans-(1R,2R)-cyclohexane-1,2-diol, leading

Comparison is made between the preparation of trans-1,2-cyclohexanediol in standard glassware (conventional batch production) and in a microreactor (continuous flow production). The reaction sequence involved two exothermic steps where the standard procedure demands slow reagent addition and careful temperature control.

Asymmetric spirocyclization based on intramolecular conjugate addition using a combination of a Lewis acid and an optically active cyclohexane-1,2-diol has been studied in connection with 1) the effect of substituents on the cyclohexane-1,2-diol and 2) the effect of substituents on
The paper reports the tin(II) chloride catalyzed reactions of diazodiphenylmethane with the cis- and trans-1,2-cyclohexanediols and R,S-1,2-propanediol in 1,2-dimethoxyethane and the identification of the monodiphenylmethyl ethers formed. The catalyst is shown to work for both the cis- and trans-cyclohexanediols, but
