The 1, 2-dithiolopyrrole 1 (thiolutine) has been obtained on two different routes. Firstly, by synthesis of the dithiolopyrrole 6a and introduction of the acetamino function into compound 6d by nitration followed by ester saponification and decarboxylation. 6d is also available from 9k by oxidative ring contraction which occurs with simultaneous dealkylation of the benzylamino group. Secondly, by synthesis of the dithiinopyrrole 15 b and introduction of ...
