Emerging Methods for the rapid determination of enantiomeric excess
TL;DR: Methods for enantiomeric excess determination using a variety of spectroscopic techniques are summarized and particular attention is paid to techniques that have promise for application to problems of combinatorial catalyst discovery but have not yet been employed.

Enantioselective Synthesis of Optically Active Pyridine Derivatives and C2-Symmetric 2,2′-Bipyridines
TL;DR: Optically active pyridine derivatives 2, 15, 18, 19, 21, 26, and 27 were obtained by enantioselective reduction of the corresponding ketones 5, 7, 11-13, 24, and 25 using the chiral borane reagent chlorodiisopinocampheylborane [(Ipc)2BCl] as mentioned in this paper.
