Pommainville, Alice published the artcileThe Synthetic Potential of Thiophenium Ylide Cycloadducts, Application In Synthesis of 111-83-1, the publication is Angewandte Chemie, International Edition (2022), 61(32), e202205963, database is CAplus and MEDLINE.
Intramol. (3+2) cycloaddition reaction between alkynyl sulfides (neutral TAC) and alkynes to provided key thiophenium ylide intermediates was first reported. These reactive species provided access to highly substituted fused thiophenes following predictable chem. sequences. Structural features on the obtained thiophenes were highly configurable by judicious choice of both alkynyl sulfide substitution and reaction conditions.
