Modifying the 5-Position of Thieno[2,3-d][1,2,3]thiadiazole-6-carboxylate Derivatives

Thieno[2,3-d][1,2,3]thiadiazole-6-carboxylates 3 belong to a new group of plant protecting agents as highly potent inducers of systemic acquired resistance (SAR). In order to obtain an enhanced basis set for structure activity relationship studies several

A new type of plant activator: Synthesis of thieno[2,3-d][1,2,3]-thiadiazole-6-carboxylic acid derivatives via Hurd-Mori cyclization

We present a short and efficient synthesis of the title compounds starting with cheap and readily available methylenebutanedioic acid and thioacetic acid. The optimised sequence allows the large-scale preparation of this new type of plant activator in a few steps. ortho-Lithiation is used for the introduction of substituents into the 5-position. A modified reaction mechanism for the Hurd-Mori reaction is suggested to explain the unexpected aromatisation.
