Concise enantioselective synthesis of abscisic acid and a new analogue

Short and high-yielding syntheses of enantiomerically pure (S)-(+) and (R)-(-)-abscisic acid are described. The syntheses proceed through key intermediates that preferentially recrystallise as single diastereoisomers for each enantiomer. This route allows the preparation of either enantiomer of abscisic acid in ca. 30% overall yield, and as demonstrated, gives access to an enantiomerically pure abscisic acid analogue.

Energy Well of Diradicals, VII. – Conjugative-Stabilized Trimethylenemethane Derivatives. Geometry Dependance of the Singlet-Triplet Splitting

For the three 2,1′-bis-allyl diradicals 3-5 the singlet-triplet splitting has been determined by the oxygen-trapping technique.In agreement with theory the value for the planar diradical is large (>14 kcal*mol-1) whereas for the orthogonal geometry the energy gap is small (6.3 kcal*mol-1).In all cases a triplet groundstate is observed.From the rotational barrier of the exo methylene groups in 6 it is shown that the interconversion of the planar and orthogonal singlet states have activation barriers (6-9 kcal mol-1) which are responsible for their kinetic stability.In contrast to 6, where the formation of the orthogonal diradical proceeds by way of the planar diradical 3, the formation of the analogous orthogonal diradical 29 from homofulvene 17 is a concerted process.This difference is an important observation with respect to the fundamental understanding of concerted and non-concerted reactions. – Key Words: Diradicals / Gas-phase kinetics / Oxygen trapping / Dynamic gas chromatography / Rotational barrier, two-step

Mechanistic Studies of Diastereoselective Cyclopropanation via Homochiral Ketals. 2. Studies with Conformationally Restricted 2-Cyclohexen-1-one Ketals

The effect of cyclohexene ring conformation on the diastereoselectivity observed for Simmons-Smith cyclopropanation of 2-cyclohexen-1-one ethylene ketals was examined by using (5S)-5-tert-butyl-2-cyclohexen-1-one 1,2-ethanediol, (2R,3R)-2,3-butanediol, and (2S,3S)-2,3-butanediol ketals.Reagent chelation by the pseudoequatorial dioxolane oxygen atom was shown to result in more effective methylene transfer.This regiochemical preference can either antagonize or reinforce diastereoselectivity due to steric hindrance of the dioxolane oxygen atoms from dissymmetric placement of methyl appendages on the dioxolane ring.

Molecular structure of butanediol isomers in gas and liquid states: Combination of DFT calculations and infrared spectroscopy studies

Density functional theory (Becke3LYP/6-311++G**) conformational analysis was carried out for all positional butanediol isomers. Taking into account the relative populations of the most stable conformers at 298.15 K, the weighted mean enthalpies of each butanediol isomer in the gas state were computed. Combining these results with the experimental values for the enthalpies of vaporization at 298.15 K, an estimate of the enthalpy of each of the butanediol isomers in the liquid state was obtained and discussed. The insight into the structural changes at the molecular level from the isolated molecule to the condensed state was improved by an infrared spectroscopy study in the OH stretching region, which was carried out for a wide range of concentrations of carbon tetrachloride solutions and pure liquids. The spectroscopic studies essentially confirmed the results derived from the combination of the computational and calorimetric studies.

Critical control by scaffold flexibility achieved in diastereodifferentiating photocyclodimerization of 2-anthracenecarboxylate

By progressively increasing the flexibility of chiral vicinal diol scaffold (from rigid cyclic tetrasaccharide to flexible 2,3-butanediol via glucose and trans-1,2-cyclohexandiol) in the diastereodifferentiating photocyclodimerization to head-to-head (HH) dimers of 2-anthracenecarboxylate on the scaffold, the anti/syn preference was dramatically inverted from 42:1 to 1:12, while the enantiomeric excess of the chiral anti-HH dimer was consistently kept high at >99% due to the excited-state dynamics that strongly disfavors the si?si enantiotopic face attack against the antipodal re?re face attack, exclusively affording the (P)-enantiomer.
