Introduction Functionalized furan-2(5H)-ones, generally called butenolides, constitute an important class of heterocyclic compounds, which are broadly found in many natural products and drugs [1–7]. Butenolides are of synthetic interest, since they show useful biological activities such as antimicrobial activity [8, 9], antifungal [10, 11], anti-inﬂammatory , anticancer [13, 14], and HIV-1 anti-viral activities [15, 16]. On the other hand, butenolides are versatile building blocks for natural product syntheses. Therefore, the synthesis of the butenolide scaffolds has gained great importance in organic synthesis, and
