Inhibitors of diacylglycerollipases and α,β-hydrolasedomaincontainingprotein6 (ABHD6) are potential leads for the development of therapeutic agents for metabolic and neurodegenerative disorders. Here, we report the enantioselective synthesis and structure activity relationships of triazole ureas featuring chiral, hydroxylated 2-benzylpiperidines as dual inhibitors of DAGLα and ABHD6. The chirality

The chemoenzymatic synthesis of three 1-deoxynojirimycin-type iminosugars is reported. Key steps in the synthetic scheme include a Dibal reduction−transimination−sodium borohydride reduction cascade of reactions on an enantiomerically pure cyanohydrin, itself prepared employing almond hydroxynitrile lyase (paHNL) as the common precursor. Ensuing ring-closing metathesis and Upjohn dihydroxylation afford
