The unnatural long-chain OPCs, OPC-9:0 and OPC-10:0, were respectively synthesized from the ethyl esters of OPC-7:0 and OPC-8:0. C2-carbon elongation was achieved via alkylation of the enolate of tert-butyl acetate. The potato tuber-inducing activity of OPC-10:0, as well as OPC-8:0, -6:0 and -4:0, was similar to that of jasmonic acid. OPC-9:0 also exhibited weak tuber-inducing activity.
非天然长链OPC,OPC-9:0和OPC-10:0,分别由OPC-7:0和OPC-8:0的
乙酯合成。通过
乙酸叔丁酯的烯醇化物的烷基化实现C 2-碳伸长。OPC-10:0以及OPC-8:0,-6:0和-4:0的马铃薯块茎诱导活性与
茉莉酸相似。OPC-9:0还表现出弱的块茎诱导活性。
