Synthesis and circular dichroism of optically active 1,3-disubstituted isochromans of dopamine D4 antagonist activity
摘要:
The C-1 epimers of the 3-methyl-6,7-dimethoxy analogues of the 04 antagonist sonepiprazole 1b and 5-HT1D agonist PNU-109291 la containing both the isochroman and p-methoxyphenylpiperazine chromophores were prepared in order to study the applicability of circular dichroism for the assignment of the configuration of 1,3-disubstituted isochromans and test their dopamine D-4 antagonist activity.
