ABSTRACT This paper describes a full conformational and stereochemical study of bicylo[3.3.1]nonanes, obtained from the reaction between cinnamaldehyde and 1-morpholine 1-cyclohexene. NMR data and stereochemistry were unequivocally established and assigned by two-dimensional experiments and single-crystal X-ray analysis. The crystal structure of a minor compound, 4, is reported. Cyclooctenes, which
摘要 本文描述了双环 [3.3.1] 壬烷的完整构象和立体化学研究,从肉桂醛和 1-吗啉 1-环己烯之间的反应中获得。核磁共振数据和立体化学是通过二维实验和单晶 X 射线分析明确建立和分配的。报告了次要化合物 4 的晶体结构。环辛烯存在于具有生物活性的天然产物中,是通过沃顿裂解法从双环壬烷合成的。

of anhydrous cerium(III) chloride was carried out. The stereochemistry of the condensed products, variously substituted 2‐morpholino‐4‐phenylbicyclo[3.3.1]nonan‐9‐ones, was deduced by using the 1H NMR COSY technique and 13C NMR data. In order to draw a general conclusion, the stereochemistry of the sterically comparable 2,4‐diphenylbicyclo[3.3.1]nonan‐9‐one was also studied in detail, using 1H NMR COSY

1-Morpholino-cyclohexen-(1) reagiert mitZimtaldehydzu 2-Morpholino-4-phenyl-bicyclo-[3.3.1]nonanon-(9) (1), wobei das nicht isolierte Diels-Alder-Zwischenprodukt 14 entsteht. Dabei werden erstmals drei der vier möglichen Stereoisomeren von 1(a–d) erhalten, deren Stereochemie durch Abbau und Umlagerung zum äquatorialen 2-Phenyl-bicyclo[3.3.1]nonan (5b) geklärt wird.
