Cyanoacetylation as a simple route for difficult accessible pyrimidines

Swellem, Randa H.,Chabaka, Laila M.,Nawwar

, p. 135 - 143 (2008/09/20)

CYANOACETYLDICYCLOHEXYLUREA was subjected to diazotization or addition reactions followed by intra-cyclizations to prepare the title ring systems. Also, transeyanoacetylation was observed upon reacting N-cyanoacctyl-3,5- dimethylpyrazole with Nor O-nucleophiles which could be utilized for the same purpose.
