A solid-phase synthesis procedure for the parallel preparation of 6,7-cycloalkane-fused 1,4-diazepane-2,5-diones is described. The methodology applies α- and alicyclic β-amino acid building blocks to construct the seven-membered heterocyclic core, while a

The first direct enzymatic method is reported for the synthesis of cis and trans βamino acid enantiomers through the lipase-catalyzed enantioselective hydrolysis of alicyclic β esters in organic media. High enantioselectivities (E usually > 001) were observed when the Candida antarctica lipase B catalyzed reactions were performed with H2O (0.5 equivalents) in iP iPr2O at 5°C. The resolved products, obtained in good yields (≥42%), could be easily separated.
