Competitive cyclization of ethyl trifluoroacetoacetate and methyl ketones with 1,3-diamino-2-propanol into hydrogenated oxazolo- and pyrimido-condensed pyridones [PDF]

Beilstein Journal of Organic Chemistry
The use of 1,3-diamino-2-propanol with competitive N- and O-nucleophilic centers in a three-component cyclization with ethyl 4,4,4-trifluoroacetoacetate and methyl ketones enables the synthesis to be carried out for octahydropyrido[1,2-a]pyrimidin-6-ones
