Enantioselective acylation of N-hydroxymethylated β-lactams in the presence of Pseudomonas sp. lipase afforded optically active precursors for the preparation of (1R,2S)- and (1S,2R)-2-aminocyclopentane- and (1R,2S,3R,4S)- and (1S,2R,3S,4R)-3-aminobicyclo[2.2.1]heptanecarboxylic acids. Due to the high enantioselectivity (E = 90 and 62) and in order to minimize the enzymatic hydrolysis of the acylated products back to the starting alcohol, the reactions were performed in acetone.
Solid-phase synthesis of 6,7-cycloalkane-fused 1,4-diazepane-2,5-diones via a cyclization/release strategy

, p. 148 - 160 (2015/12/23)
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
