概要

• 論文の詳細を見る

• The title pyrimidoazepines when treated with phosphoryl chloride underwent rearrangement to the vinylpyrrolo-pyrimidines <I>via</I> probable intermediates 5-(2-benzylaminoethyl)-4-chloro-6-vinylpyrimidines. Reduction and subsequent dehydrogenation of the products led to the preparation of 4-ethyl-7<I>H</I>-pyrrolo[2,3-<I>d</I>]pyrimidines and their 5,6-dihydro derivatives. The structures are discussed on the basis of p<I>K</I><SUB>a</SUB> values, UV and NMR spectra.
