brought about simultaneous 1,3-dipolar cycloaddition of the resulting nitrone to allyl alcohol to give three diastereoisomeric adducts, from which (+)-febrifugine and (+)-isofebrifugine, potent antimalarial alkaloids, were synthesized.
(S)-2-(叔丁基二苯基甲硅烷氧基)-5-(甲磺酰氧基)戊醛与羟胺在烯丙醇中的反应可同时将生成的腈与烯丙醇进行1,3-偶极环加成反应,制得三种非对映异构体加合物,(合成了有效的抗疟疾生物碱+)-非贝非新和(+)-异非贝新。
