Synthesis of (3S,5R)-3,5-diaminoazepan-2-one as a conformationally restricted surrogate of the Dab-Gly dipeptide
摘要:
An efficient and stereospecific synthesis of chiral 3,5-diaminoazcpan-2-one as a novel conformationally restricted surrogate of 2.4-diaminobutanoyl (Dab)-Gly dipeptide has been achieved by ail intramolecular transamidation with a catalytic hydrogenation as the key steps, starting from commercially available trans-4-hydroxy-L-proline. This methodology represents a powerful tool for the synthesis of the Dab-Gly dipeptide surrogate as one type of Freidinger epsilon-lactam. epsilon 2005 Elsevier Ltd. All rights reserved.
