Abstract
![]()
Optically pure epoxides
are recognized as highly valuable products
and key intermediates, useful in different areas from pharmaceutical
and agrochemical industries to natural product synthesis and materials
science. The predictable fate of the ring-opening process, in terms
of stereoselectivity and often of regioselectivity, enables useful
functional groups to be installed at vicinal carbon atoms in a desired
manner. In this way, products of widespread utility either for synthetic
applications or as final products can be obtained. The advent of asymmetric
organocatalysis provided a new convenient tool, not only for their
preparation but also for the elaboration of this class of heterocycles.
In this review, we focus on recent developments of stereoselective
organocatalytic ring-opening reactions of meso-epoxides,
kinetic resolution of racemic epoxides, and Meinwald-type rearrangement.
Examples of asymmetric organocatalytic processes toward specific synthetic
targets, which include ring opening of an epoxide intermediate, are
also illustrated.

Abstract
A novel three-step four-transformation approach to highly functionalized 5-amino-3,4-dihydro-2H-pyrrole-2-carboxylic acid esters, starting from commercially available phenylsulfonylacetonitrile, aldehydes, and N-(diphenylmethylene)glycine tert-butyl ester, was developed. The one-pot strategy delivered this class of amidines bearing, for the first time, three contiguous stereocenters, in good to high yield and diastereoselectivity. The entire sequence was carried out using diethyl carbonate and 2-methyl tetrahydrofuran as benign solvents, operating under metal-free conditions. The process could be conveniently scaled-up, and the synthetic utility of the products was demonstrated.

Abstract
New chiral porphyrin imine was synthesized from (S)-3-benzyl-2-methyl-4-phenylbutanal according to dipyrromethane method using trifluoroacetic acid, BF3 etherate, and p-chloranil. Manganese complex of this chiral porphyrin imine ligand was used as catalyst in the asymmetric epoxidation of styrene derivatives possessing different substituents. Styrene derivatives possessing electron withdrawing groups gave the corresponding chiral epoxides in high yield up to 98% and ee up to 99%. The mechanism for the catalytic asymmetric epoxidation was also discussed based on transfer of oxygen.

Abstract
Existing stereoselective routes to 2,5-cyclohexadienones involve either desymmetrization of an achiral substrate or have attempted to perform an asymmetric dearomatization of a phenol. Herein, we report proof-of-principle experiments aimed at developing a kinetic resolution as an alternative method for accessing enantioenriched 2,5-cyclohexadienones. More specifically, chiral bifunctional thiourea catalysts were used to promote the addition of 2-thionapthalene into unsymmetric para-quinols. The selectivity of the kinetic resolution was found to be quite sensitive to substitution around the substrate.

Abstract
Nitroepoxides are easily transformed into benzodiazepines, tetrahydrobenzodiazepines, imidazopyridines, and N-alkyl tetrahydroquinoxalines by treatment with 2-aminobenzylamines, 2-aminopyridines, and N-alkyl 1,2-diaminobenzenes, respectively. Regioselectivity is controlled through attack of the most nucleophilic nitrogen of the unsymmetrical diamine to the β position of the epoxide. These reactions represent an efficient way to prepare privileged bioactive structures.
