Synthese totalgeschützter, nichtproteinogener α-Aminosäuren und Oligopeptide aus 2H-1,3-Oxazinen und 2H-1,3-Benzoxazinen via Ugi-Reaktion
摘要:
The preparation of six-membered N,O-heterocyclic 2H-1,3-oxazines 1 and 2H-1,3-benzoxazines 2 and the use of them in the synthesis of the corresponding alpha-amino acids 3a-c, 4a-c and oligopeptides 3d,e, 4d-f are described These compounds are prepared based on the Ugi four-component-condensation reaction.
