Intramolecular cyclization of 1-(3-bromopropyl)uracils
Abstract
The intramolecular O-alkylation of 1-(3-bromopropyl)uracils proceeds smoothly in basic conditions and yields cyclic ethers as the major products. This reaction competes with the intermolecular N-alkylation of uracil and its derivatives. The mechanism of this reaction is also discussed in terms of reactivity indices calculated using the HMO method.
