Enantioselective rhodium(I)-triethylamine catalyzed addition of potassium isopropenyl trifluoroborate to enones
摘要:
A general process is reported for the highly enantioselective 1,4-addition of isopropenyl trifluoroborate to cyclic enones under catalysis by a chiral Rh(l) complex and triethylamine at room temperature. (C) 2008 Elsevier Ltd. All rights reserved.
