Johnson-type acetals derived from dimethyl tartrate give, after opening with Me2BBr and cuprate displacement, secondary alcohols with high diastereoselectivity (>30:1). The mechanism proposed for the induction of diastereoselectivity is downstream from the ring fission. It implies a direct participation of the Lewis acid as a source of nucleophile and the stereospecific transformation of the resulting bromo acetal through an invertive and temperature-dependent process. The acetals are prepared by reaction of the desired aldehyde with dimethyl tartrate. Removal of the auxiliary is accomplished through Sml2 reduction or by an addition – elimination protocol using methoxide.

A Pd(0)-catalyzed Hiyama coupling reaction of tetrafluoroethylene (TFE) proceeded without the use of a base to give alpha,beta,beta- trifluorostyrene derivatives. A Ni(0)-catalyzed Hiyama coupling reaction of perfluoroarenes also occurred without a base. The key intermediate in these reactions would be a transition-metal fluoride complex that is generated in situ by the oxidative addition of a C-F bond.

The present invention includes a process for enantioselective preparation of a non-racemic compound, which is either usable as a fragrance or flavor component or is convertible to a fragrance or flavor component by one or more additional reaction steps. The process includes the step of contacting either a substrate capable of forming a non-racemic compound by an enantioselective reaction and a co-reactant in the presence of a non-racemic catalyst, or a non-racemic or enantiopure substrate and a co-reactant, optionally in the presence of a racemic or non-racemic catalyst. The contacting is carried out at a temperature and length of time that is sufficient to produce the non-racemic compound with high optical purity. The process is used in stereoselective preparation of enantiomerically enriched intermediates useful in the preparation of non-racemic, chiral flavor and fragrance components.

A new dinuclear chiral Co(salen) complexes bearing group 13 metals have been synthesized and characterized. The easily prepared complexes exhibited very high catalytic reactivity and enantioselectivity for the asymmetric ring opening of epoxides with H2O, chloride ions and carboxylic acids and consequently provide enantiomerically enriched terminal epoxides (>99% ee). It also catalyzes the asymmetric cyclization of ring opened product, to prepare optically pure terminal epoxides in one step. The homogeneous dinuclear chiral Co(salen) have been covalently immobilized on MCM-41. The potential benefits of heterogenization include facilitation of catalyst separation and recyclability requiring very simple techniques. The system described is very efficient.

A palladium-catalyzed intermolecular vicinal diarylation of terminal 1,3-dienes using aryldiazonium tetrafluoroborates and arylboronic acids is reported. Using this technology, two different arenes are regioselectively introduced in a vicinal fashion across the terminal alkene of a variety of terminal 1,3-dienes at ambient temperature. Through the action of a chiral bicyclo[2.2.2]octadienyl ligand at -20 C, good enantioselectivity has also been achieved.
