Abstract

5-Formyluracil derivatives and their Schiff bases with chiral amino alcohols undergo highly diastereoselective 1,2- and 1,3-allylations. The absence of the C-4 carbonyl in the case of 2,4-dimethoxy-5-formylpyrimidine and itsSchiff bases leads to loss of diastereoselectivity. (C) 2001 Elsevier Science Ltd. All rights reserved.
