Synthesis of 2-furilpergidroaza heterocycles and their transformation under the influence of anhydrides unsaturated's acids

The reaction of cycloaddition of furan fragment with various dienophiles has been discussed. This work is a continuation of studies of the effect size of the loop on the direction of this interaction if the furan fragment is in the α-position. We synthesized cyclic α-furilsubstituted amines, and the example of their interaction with cinnamoyl chloride and allyl bromide studied intramolecular cycloaddition reaction.The case of disclosure of a saturated cycle α-methoxy carbamate by the excess of acid, resulting in the formation of difuriles derivatives has been studied.
