, m, n, W, X, Y, Z and L as defined herein, their pharmaceutical compositions and methods of use. These novel compounds inhibit the processing of amyloid precursor protein (APP) by β-secretase and, more specifically, inhibit the production of Aβ-peptide. The present disclosure is directed to compounds useful in the treatment of neurological disorders related to β-amyloid production, such as Alzheimer's disease and other conditions affected by anti-amyloid activity.
Lipase-Mediated Resolution of trans-1-Azidoindan-2-ol: A New Route to Optically Pure cis-1-Aminoindan-2-ol

Optically pure trans-1-azidoindan-2-ol has been prepared in both enantiomeric forms via lipase-mediated kinetic transesterification in organic solvent. A route to optically pure cis-1-aminoindan-2-ol has also been developed by using the optically pure trans-azidoalcohol thus obtained.

established a cascade for the asymmetric azidohydroxylation of styrene derivatives leading to chiral substituted 1,2-azido alcohols via enzymatic asymmetric epoxidation, followed by regioselective azidolysis, affording the azido alcohols with up to two contiguous stereogenic centers. A newly isolated two-component flavoprotein styrene monooxygenase StyA proved to be highly selective for epoxidation

A series of 1,2-amino alcohol and 1,2-monotosylated diamine derivatives of indane have been applied as ligands in the asymmetric ruthenium(II)-catalysed transfer hydrogenation reaction of a series of ketones. Of these, the cis-1-aminoindan-2-ol derivative gives some of the highest asymmetric inductions reported for any amino alcohol ligand in this application.
