Photolysis of 4-substituted-4-hydroxy-3-cyclobuten-1-ones undergo electrocyclic ring opening followed by ring closure to provide butenolide products.This transformation is envisaged to involve a stereoselective disrotatory electrocyclic ring opening to co

Go with the flow: 4-Hydroxycyclobutenones were efficiently transformed into 5H-furanones using an inexpensive flow-photochemical setup. The results challenge the notion that this and the related thermochemical rearrangement display torquoselectivity in th
