The synthesis of 1,2,3-trisubstituted cyclopenta[b]thiophenes was achieved through a Bronsted acid mediated domino process under solvent-free conditions. In this one-pot process, benzothienylation of 1,3-dicarbonyls follows an intramolecular aldol-type reaction leading to the generation of functionalized and highly substituted annulated benzothiophenes. This class of compounds find potential applications
1,2,3-三取代环戊二烯[b]噻吩的合成是在无溶剂条件下通过布朗斯台德酸介导的多米诺过程实现的。在这个一锅法中,1,3-二羰基的苯并噻吩基化遵循分子内醇醛型反应,导致生成官能化和高度取代的环化苯并噻吩。这类化合物在分子电子学中有潜在的应用,并表现出显着的生物活性。一项简短的理论研究确定了区域异构体的能量与其分布之间的重要关系。
