Estrogen receptor ligands. Part 9: Dihydrobenzoxathiin SERAMs with alkyl substituted pyrrolidine side chains and linkers
摘要:
A series of dihydrobenzoxathiin SERAMs with alkylated pyrrolidine side chains or alkylated linkers was prepared. Minor modifications in the side chain or linker resulted in significant effects on biological activity, especially in uterine tissue.
A new method for stereoselective oxidation of chiral 2-pyrrolidino-1-ethanol derivatives to oxazolopyrrolidines using trimethylamine-N-oxide in the presence of iron carbonyls
摘要:
Chiral 2-pyrrolidino-1-ethanol derivatives were oxidatively cyclized to the corresponding oxazolopyrrolidines, with excellent stereoselectivity by treatment with excess Me3NO in the presence of 20% of an iron carbonyl complex. (c) 2005 Elsevier Ltd. All rights reserved.
