A facile reduction of 2-aminopyrimidines with triethylsilane and trifluoroacetic acid
摘要:
2-Aminopyrimidines were facilely reduced to 2-amino-dihydro- or 2-amino-tetrahydropypryrimidines with triethylsilane and trifluroacetic acid in high yields. By controlling the equivalents of reducing reagents and temperature, selective reduction could also be achieved for some substrates. (C) 2004 Elsevier Ltd. All rights reserved.
