摘要

The reaction of PhN, and aromatic thioketoiies 18 (two-component reaction) at 80” yields only the corresponding imines 22, S, and N2. Under similar conditions, in the prescnce of sterically crowded 2, 2, 4, 4-tetramethylcyclobutanethiones 19 (three-component reaction), 1, 2, 4-trithiolanes of type 20 are formed in good yields in addition to iinines 22 (Scheme 4). In case of 19a and 19c (X= CO, CS), the symmetrical trithiolanes 21a and 21b, ...
