Cyclizations 2 + 2 + 2 Cycloadditions, carbon disulfide

Azine approach. 1 -Pyridinimines undergo 1,3-dipolar cycloaddition reactions with thiones. In the reaction between 2-isoquinolinimine and carbon disulfide the mesoionic thiadiazole (716) is formed the formation of (716) involves a secondary dehydrogenation of the initial adduct. With diphenyl thionocarbonate, phenoxy group expulsion is succeeded by cyclization leading to the adduct (717) (62TL387). [Pg.743]
