The polyhydroxylated beta-amino acids (2S,3R,4S,5S,7E)-3-amino-8-phenyl-2,4,5-trihydroxyoct-7-enoic acid (APTO) and (2S,3R,4S,5S,7E,9E)-3-amino-10-(4-ethoxyphenyl)-2,4,5-trihydroxydeca-7,9-dienoic acid (AETD) are key components of the microsclerodermin family of anti-fungal cyclic peptides. They have been synthesised in protected form in twelve steps using a unified strategy, with the introduction
多羟基化的β-氨基酸(2S,3R,4S,5S,7E)-3-氨基-8-苯基-2,4,5-三羟基辛-7-烯酸(APTO)和(2S,3R,4S,5S ,7E,9E)-3-氨基-10-(4-乙氧基苯基)-2,4,5-三羟基癸-7,9-二烯酸(AETD)是抗真菌环状肽微菌皮家族的关键成分。它们已使用统一策略以十二个步骤以保护形式合成,并在合成的最后一步中从常见的醛中间体引入不饱和侧链。合成的特征是不对称氨基羟基化和二羟基化反应的有序应用,以高选择性有效地引入了靶标的立体化学。
