A35512B是最近从链霉菌(Streptomyces Candidus)分离的糖肽抗生素A35512复合物的成分之一。用6 N HCl水解糖苷配基,得到放线基己二酸(6)和先前报道的含Cl的二苯醚型双(苯基甘氨酸)2。糖苷配基在57%HI中的水解产生了6,tris(氨基酸)5b,这是由于2的脱卤作用而形成的氨基酸5a的β-OH基团和7氨基酸的还原所致。氨基酸2和7被氧化降解为双(苯甲酸酯)3d和10。3d和10的结构通过独立合成得到证实。氨基酸2被分配结构2d而不是先前提出的结构2a或2b。的绝对构型2D被确定为[R为对位羟基化环和小号的元羟化环。

and amino acid 7, formed by dehalogenation of 2. Amino acids 2 and 7 were oxidatively degraded to bis(benzoates) 3d and 10. The structures of 3d and 10 were confirmed by independent syntheses. Amino acid 2 is assigned structure 2d rather than the previously proposed structures 2a or 2b. The absolute configuration of 2d was determined as R for the para-hydroxylated ring and S for the meta-hydroxylated
