aliphatic aldehydes have been isolated from the roots of Cirsium dipsacolepis, viz. 7-octenal, (2 E )-2,8-nonadienal, (2 E )-2,9-decadienal, (2 E )-2,10-undecadienal, (2 E ,4 E )-2,4,10-undecatrienal, (2 E ,4 E )-2,4,11-dodecatrienal, (2 Z ,4 Z )-2,4,11-dodecatrienal and (2 E ,4 Z )-2,4,11-dodecatrienal. The aldehydes were identified and synthesized stereoselectively from alkane-α,ω-diynes.
摘要 已经从 Cirsium dipsacolepis 的根中分离出两种新的和六种已知的脂肪醛,即。7-辛烯醛、(2 E )-2,8-壬二烯醛、(2 E )-2,9-癸二烯醛、(2 E )-2,10-十一烯醛、(2 E ,4 E )-2,4,10 -十一碳三烯醛、(2 E ,4 E )-2,4,11-十二碳三烯醛、(2 Z ,4 Z )-2,4,11-十二碳三烯醛和 (2 E ,4 Z )-2,4,11-十二碳三烯醛. 从烷烃-α,ω-二炔中立体选择性地鉴定和合成醛。
