(1R, 6S, 7S, 11R)-(+)-Biflora-4, 10(19),15-triene was synthesized starting from (r)-(+)-citronellic acid. This enabled us to assign (1S), 6R, 7R, (11S)-stereochemistry to the naturally occurring (-)-enantiomer isolated from soldiers of the termite species Cubitermes umbratus.
从(r)-(+)-香茅酸开始合成(1 R,6 S,7 S,11 R)-(+)-Biflora-4,10(19),15-三烯。这使我们能够将(1 S),6 R,7 R,(11 S)-立体化学分配给从白蚁物种Cubitermes umbratus士兵分离的天然(-)-对映异构体。
