Some ring expansion–ring contraction reactions of ethyl 4-chloromethyl-1,2,3,4-tetrahydro-6-methyl-2-oxopyrimidine-5-carboxylate
Abstract
Reaction of the title chloromethylpyrimidine with potassium hydrosulphide yields a sulphur-bridged 1,3-diazepin-2-one; in contrast, reaction with various amines give rise to α-aminopyrrolines and controlled reaction with hydroxide an α-hydroxypyrroline.
