A process for preparing a halohydrin of a water-miscible olefin comprising: reacting a water-miscible olefin in water with a compound of the formula (I)
wherein R1 and R2 independently represent a branched or unbranched, substituted or unsubstituted, lower alkyl having from 1 to 5 carbons and X is a halogen, to thereby form the halohydrin of the water-miscible olefin.

The present invention relates to compounds of e.g. formula (I) as BCL-2 inhibitors for the treatment of neoplastic, autoimmune or neurodegenerative diseases. Preferred compounds are e.g. fused 1H-pyrrolo[2,3-b]pyridine derivatives of e.g. formula (II)
The lipase catalyzed resolution of cis and trans-3-amino-4-hydroxytetrahydraurans and cis-3-amino-4-hydroxypyrrolidines have been studied. For all the heterocycles, the best enantioselectivity was obtained using Candida antarctica lipases A and B as catalysts in hydrolytic processes. The absolute configuration of the optically pure obtained heterocycles has been assigned. (C) 2014 Elsevier Ltd. All rights reserved.

Oxetanes offer exciting potential as structural motifs and intermediates in drug discovery and materials science. Here an efficient strategy for the synthesis of oxetane rings incorporating pendant functional groups is described. A wide variety of oxetane 2,2‐dicarboxylates were accessed in high yields, including functionalized 3‐/4‐aryl‐ and alkyl‐substituted oxetanes and fused oxetane bicycles. Enantioenriched
