production of heterocycles. These polyfunctional compounds can be represented by the
formula R3–CH2CS–NR1R2 (where R1, R2 = H, Alk, Ar; R3 is an electron-withdrawing …
As a rule the products of these heterocyclizations contain functional groups, which makes it
possible to achieve their modification or annelation. Such characteristics of thioamides with
an active methylene group substantially increase their synthetic potential and extend the …
