Insight into the structure of antitubercular Callyaerins: conformational studies and synthesis of a unique dehydroamino acid, β-aminodehydroalanine
{{output}}
β-Aminodehydroalanine, ΔAla(β-NH), (2,3-diaminoprop-2-enoic acid), is a unique dehydroamino acid and a central component of Callyaerins A-M and Callynormine A. The presence of this unusual structural element containing an enamine functional group may be rel... ...
