The synthesis of (+)-and(−)-flesinoxan: Application of enzymatic resolution methodology
摘要:
The synthesis of (+/-)-flesinoxan was carried out in seven steps starting from catechol. An enzymatic resolution was utilized to prepare each enantiomer. Based upon the known preferences of the enzyme system used, we have assigned the (R)-configuration to the (+)-flesinoxan isomer.

A series of 2-phenylpyrrole Mannichbases was synthesized and screened in pharmacological models for antipsychotic activity and extrapyramidal effects. Structure modifications of 5-(4-fluorophenyl)-2-[[4-(2-methoxyphenyl)-1-piperazinyl]methyl]pyrrole (1), the prototype of a new class of sodium-independent atypical dopamine D-2 antagonists, resulted in 2-[[4-(7-benzofuranyl)-1-piperazinyl]methyl]-5
