An efficient flow-photochemical synthesis of 5H-furanones leads to an understanding of torquoselectivity in cyclobutenone rearrangements
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

PHOTOLYSIS OF 4-SUBSTITUTED-4-HYDROXY-3-CYCLOBUTEN-1-ONES: A NEW ROUTE TO BUTENOLIDES FROM 4-HYDROXYCYCLOBUTENONES
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

General Regiospecific Synthesis of Annulated Quinones
A general regiospecific synthesis of annulated hydroquinones/quinones is presented.This specifically involves the thermal rearrangement of the 4-aryl-4-hydroxycyclobutenones 1a-k to the corresponding annulated hydroquinones.The synthetic scope and mechani
