The synthesis of several 11-substituted-5,6-dihydro-11H-dibenzo[b,e]azepin-6-ones, and an improved method of preparing 5-cyano-10,11-dihydro-5H-dibenzo[a,d]cycloheptene and 12-cyano-5,6,7,12-tetrahydrodibenzo[a,d]cyclooctene are described.A description of the synthesis of epoxides from diaryl ketones and dimethylsulfonium methylide by a modified technique is given.The nuclear magnetic resonance spectra of several of the 11-substituted dibenzo[b,e]azepin-6-ones are interpreted on the basis of a slow interconversion between diastereomeric boat conformers in which the C-11 substituent is quasi axial or quasi equatorial.
本文描述了几种11-取代-5,6-二氢-11H-二苯并[b,e]氮杂环-6-酮的合成方法,以及改进的制备5-氰基-10,11-二氢-5H-二苯并[a,d]环庚烯和12-氰基-5,6,7,12-四氢二苯并[a,d]环辛烯的方法。此外,还介绍了一种改良技术,用于从二芳基酮和二甲基亚砜甲基化物制备环氧化物。基于C-11取代基准轴或准赤道的船型异构体之间缓慢的互变,解释了几种11-取代二苯并[b,e]氮杂环-6-酮的核磁共振谱。
