Synthesis of 3‐azabicyclo[3.2.0]heptane‐derived building blocks via [3+2]cycloaddition of cyclobutene‐1‐carboxylate and azomethine ylide is described. It is shown that the title bicyclic scaffold is a three‐dimensional template which is well‐compatible with lead‐oriented parallel synthesis.
The present invention relates to herbicidally active thiadiazole derivatives, as well as to processes and intermediates used for the preparation of such derivatives. The invention further extends to herbicidal compositions comprising such derivatives, as well as to the use of such compounds and compositions in controlling undesirable plant growth: in particular the use in controlling weeds, in crops of useful plants.

unsubstituted in the 5-position, and a strong base such as an organolithium compound, sodamide, sodium methylsulfinyl carbanion, or potassium t-butoxide results in cleavage of the thiadiazole ring system with evolution of nitrogen and formation of alkalimetal alkynethiolate. Subsequent addition of an alkyl or acyl halide to the reaction mixture produces 1-alkynyl thioethers. 4-(5-Phenyl-1,2,3-thiadiazolyl)lithium
