Title: Synthesis and absolute configuration of the enantiomers α-aminoethylcymantrene and some of its derivatives
Abstract: Resolution of α-aminoethylcymantrene (I) to its enantiomers has been effected for the first time by means of (+)-d-tartaric acid. The molecular structure and absolute configuration of (+)-(R)-α-(N-acetylamino)ethylcymantrene prepared from ()-I have been established by an X-ray analysis. On the basis of chemical and chiroptical correlation methods the R-configuration of the chiral centre is also assigned to ()-I, (+)-α-(N,N-dimethylamino)ethylcymantrene, (+)-II, and (+)-α-(N,N,N-trimethylammonium)ethylcymantrene iodide, (+)-III. ORD and CD curves of the prepared optically active compounds have been studied
