Facile synthesis of optically active cis-2,5-diphenyl-1,4-diazabicyclo[2.2.2]octane
摘要:
Enantiomerically pure (1R,2R,4R,5R)- and (1S,2R,4S,5R)-2,5-diphenyl-1,4-diazabicyclo[2.2.2]octane (2,5-diphenyl-DABCO) have been prepared and their crystal structures studied. Copyright (C) 1996 Elsevier Science Ltd
This invention relates to fluorinating agents and, more particularly, to chiral non-racemic fluorinating agents useful for enantioselective fluorination, as well as to their synthesis and use and other subject matter. The fluorinating agents are based on a substituted 1,4-diazabicyclo[2.2.2]octane (DABCO) skeleton and provide electrophillic fluorine enantioselectively.
