Abstract
Diastereo- and enantioselective kinetic resolution of racemic planar-chiral 1-R-2-vinylferrocenes (rac-1) was attained by the molybdenum-catalyzed asymmetric metathesis dimerization (AMD). Two sequential AMD reactions of rac-1a (R = Br) provided (E)-(S,S)-1,2-di(2-bromoferrocenyl)ethylene in >99% ee, which was converted to (S,S)-1,2-bis[(2-diphenylphosphino)ferrocenyl]ethane (S,S)-5. Planar-chiral bisphosphine (S,S)-5 coordinated to a dichloropalladium(II) fragment in a trans-chelating fashion, which was applied as a chiral ligand in the palladium-catalyzed asymmetric allylic alkylation showing enantioselectivity of up to 90% ee.

Abstract
Winding vine-shaped bithiophene was synthesized through the nosyl (2-nitrobenzenesulfonyl) cyclization protocol. The reaction of bithiophene bearing bromomethyl groups at the 3,3'-positions with nosylated 1,2-ethylenediamine in the presence of potassium carbonate afforded the annulated product in excellent yield. The obtained bithiophene was found to contain a 10-membered ring, which was confirmed by X-ray analysis. The related nosyldiamine bearing a tri- or tetramethylene group also reacted in a similar manner, affording an 11- or 12-membered macrocycle, respectively.

Abstract
The chirality of winding vine-shaped heterobiaryls with molecular asymmetry is recognized by a sugar-based chiral oxidant. Kinetic resolution of (±)-bisbenzoimidazole bearing an olefin moiety takes place with Shi's asymmetric epoxidation to observe krel value up to ca. 35 affording the corresponding epoxide. The reaction of a (±)-bithiophene derivative also recognized the chirality to give the corresponding epoxide with er of 96:4 at 39% conversion. Dynamic kinetic resolution is found to take place when unsymmetrical biaryl composed of benzoimidazole/thiophene is subjected to Shi's epoxidation, whose conversion of the racemic substrate exceeds to 50%.
