nerol, and(E,E)-farnesol— with Atkinson'sN-acetoxyamino-2-ethyl-4(3H)-quinazolonereagent (4) affordedN-substituted2,3-epimino alcohols. Reduction of these and relatedN-substitutedaziridines with metal-ammonia or lithium-naphthalenide reagents furnished a series of N-H aziridino alcohols (53–74%) including 2,3- and 6,7-epimino geraniols (10 and13), 2,3-epimino nerol (17),(E,E)-2,3-epiminofarnesol (23)
用Atkinson's N-乙酰氧基氨基-2-乙基-4(3H)-喹唑啉酮试剂(4)对异戊二烯醇(香叶醇,神经醇和(E,E) -法尼醇)进行羟基定向的叠氮化,得到N-取代的2,3-表氨醇。用金属氨或萘锂试剂还原这些和相关的N-取代的氮丙啶类化合物提供了一系列NH叠氮基丁醇(53-74%),包括2,3-和6,7-表皮香叶醇(10和13),2 3-表皮神经醇(17),(E,E) -2,3-表皮法尼醇(23)和syn -2,3-表皮异佛尔醇(20)。还报道了通过辐射烯丙基叠氮基甲酸酯和水解恶唑烷酮光产物,效率较低的反式-2,3-表皮异戊二烯醇10和23的合成。这些方法补充了用于合成类异戊二烯多烯的NH氮丙啶的已知方法。
