A method for determining the absolute configuration of β-chiral primary alcohols has been developed. Enantioenriched alcohols were acylated in the presence of either enantiomer of the enantioselective acylation catalyst HBTM, and the faster reaction was determined by measuring product conversion using 1H NMR spectroscopic analysis. An empirical mnemonic was developed that correlates the absolute configuration of the alcohol to the faster reacting catalyst. Successful substrates for this method include primary alcohols that bear a "directing group" on the stereogenic center; directing groups include arenes, heteroarenes, enones, and halides.
Formal synthesis of (+)-crocacin C
Pasqua, Adele E.,Ferrari, Frank D.,Crawford, James J.,Marquez, Rodolfo
, p. 2114 - 2116 (2012/07/13)
The formal synthesis of (+)-crocacin C is reported. The approach described takes advantage of a highly regioselective epoxide cuprate addition and a diastereoselective Overman rearrangement. The synthesis is practical and amenable to scale up.

Page/Page column 32-33, (2008/12/06)
The present invention relates to furan derivatives of formula (I), their method of synthesis and uses thereof. Concretely, the compounds disclosed have proved to be inhibitors of glycogen synthase kinase 3β, GSK-3 β, which is known to be involved in different disease and conditions, such as Alzheimer's disease or non-insulin dependent diabetes mellitus. The present invention also relates to pharmaceutical compositions comprising the same. Further, the present invention is directed to the use of the compounds in the manufacture of a medicament for the treatment and/or prevention of a GSK-3 mediated disease or condition.
Highly Felkin-Anh Selective Hiyama Additions of Chiral Allylic Bromides to Aldehydes. Application to the First Synthesis of Nephromopsinic Acid and Its Enantiomer
Mulzer, Johann,Kattner, Lars,Strecker, Achim R.,Schr?der, Christian,Buschmann, Jürgen,Lehmann, Christian,Luger, Peter
, p. 4218 - 4229 (2007/10/02)
The chromium(II)-mediated addition ("Hiyama reaction") of the chiral allylic bromides 13, 15, 19, 22, 24, and 27 to achiral and chiral aldehydes proceeds with high Felkin-Anh selectivity with respect to the stereocenter at Cγ in the bromide (Table II). By
