    Chemical modification of plant alkaloids. I. Aminomethylation of barbituric acid derivatives by cytisine
    摘要:
    Reaction of cytisine with 1-mono- and 1,3-disubstituted 5-arylmethylbarbituric acids in the presence of formaldehyde results in aminomethylation of C-5 to form the corresponding 5-cytisylmethylbarbituric acids. The structures of the products are found using PMR spectroscopy mid mass spectrometry. 1-Phenyl-5-(2,4-dimethoxybenzyl)-5-cytisylmethylbarbituric acid is obtained as a mixture of two steroisomers in an approximately 2:1 ratio.

    diastereoselective synthesis of perfluoroalkylated cis-spiropyrido[2,1-a]isoquinoline-1,5’-pyrimidine derivatives in good to excellent yields under mild conditions. The reaction mechanism was proposed to illustrate the formation of the diastereoisomers and proton-promoted transformation of trans-spiropyrido[2,1-a]isoquinoline-1,5’-pyrimidines to the more thermodynamically stable cis-isomers.
