摘要：Synthesis of 2-N-heptyl-5,9-dimethyl-6,7-benzomorphan from 3,4-lutidine was effected in three step process and only a-form could be obtained through phosphoric acid cyclisation. This a-form of benzomorphan was converted in three steps to a-2N-hepthyl-2-hydroxy-5,9-dimethyl-6,7-benzomorphan, which was also synthesised from alternative route. Infrared spectrum of the base confirmed the presence of a-from.
