Asymmetric heterocyclocondensation of polyfluorinated aldehydes catalysed by a chiral titanium(IV) complex
摘要:
The Binol/Ti(OiPr)(4) chiral titanium complex catalyses the asymmetric cyclocondensation of polyfluoroalkylaldehydes with the Danishefsky's diene leading to chiral polyfluoroalkyl dihydropyrenones with high enantiomeric excesses. (C) 2000 Published by Elsevier Science Ltd.
