실험 절차

As an example, D-(-)-(4-hydroxyphenyl)-glycine and D-(-)-phenylglycine are key intermediates in the industrial synthesis of amoxycillin and ampicillin respectively; while D-(-)-2-amino-2-(1,4-cylcohexadien-1-yl)acetic acid may conveniently be employed in the acylation of 7-amino-cephalosporanic acid to give cefradin.
