Synthesis of (-)-gloeosporone (1a), isolated from spores of Colletotrichum gloeosporioides as a self-inhibitor for germination, and its three diastereomers was accomplished starting from (S)- and (R)-1-tridecen-8-ol obtained from their (S)-naphthyl ethylcarbamates (8a and 8b), both of which were isolated from the mixture of diastereoisomers derived from racemic 1-tridecen-8-ol (7) and the Pirkle reagent. Biological testing of the compounds showed weak self-inhibitor activity toward germination of the spores.
从(S)-和(R)-1-十三碳烯-8-醇开始,这两种醇均是从消旋1-十三碳烯-8-醇(7)与Pirkle试剂所形成的非对映异构体混合物中分离得到的(S)-萘乙基氨基甲酸酯(8a和8b),成功合成了从Colletotrichum gloeosporioides菌孢子中分离得到的自抑制萌发剂(-)-gloeosporone(1a)及其三种非对映异构体。生物测试显示这些化合物对孢子萌发具有较弱的自抑制活性。
