摘要
Synthesis of two new amino acids, containing pyran rings, is reported from carbohydrate derivatives. The cis-3-amino-pyran-2-carboxylic acid (cis-APyC) was prepared from (R)-glyceraldehyde derivative, using nucleophilic substitution reaction for pyran ring formation. Similarly, the trans-3-aminoxy-5,6-dihydro-2H-pyran-2-carboxylic acid (trans-AmPyC) was prepared from diacetone glucose (DAG), using ring closing metathesis (RCM) reaction for the ring formation.
