A small and structure-biased library of enantiopure anti-β-amino alcohols was prepared in a straightforward manner by a simplified version of the Reetz protocol. Antiproliferative activity testing against a panel of five human solid tumor cell lines gave GI50 values in the range 1-20 μM. The reverse screening by computational methods against 58 proteins involved in cancer pointed to kinases as possible therapeutic target candidates. The experimental determination of the interaction with 456 kinases indicated that the compounds behave as selective CK1ε inhibitors. Our results demonstrate that the lead compound represents the first selective CK1ε inhibitor with proven antiproliferative activity in cancer cell lines.

Enantiomerically pure N,N-dibenzyl-α-amino aldehydes reacted with (chloromethyl)lithium, generated in situ from bromochloromethane and lithium metal, to give predominantly erythro aminoalkyl epoxides. Treatment of the crude epoxides with aqueous hydrochloric acid gave crystalline (2S,3S)-N,N-dibenzylamino chlorohydrin hydrochlorides in 32-56% overall yield and high isomeric purity. These compounds are versatile synthetic intermediates for the preparation of hydroxyethylamine-based HIV protease inhibitors, either directly as such, or via conversion to the corresponding N-Boc(2S,3S)-aminoalkyl epoxides. The processes described do not make use of hazardous reagents or intermediates, do not require chromatographic purifications, and are thus amenable to the preparation of large quantities of these versatile building blocks.
