Abstract

The crotonic condensation of caffeine-, isocaffeine-, and theobromine-8-aldehydes with 3-methyl-, 3-ethyl-, 3-allyl-, and 3-phenylrhodanines in the presence of piperidine with brief heating in methanolic and methanolic-acetic acid solutions has been studied. Purine derivatives of the rhodanines have been synthesized.
