Resveratrol (1) reacts with singlet oxygen by two major pathways: A [2 + 2] cycloaddition forming a transient dioxetane that cleaves into the corresponding aldehydes and a [4 + 2] cycloaddition forming an endoperoxide that, upon heating, undergoes a rearrangement to moracin M. The rate constant by which singlet oxygen is removed by 1 (kT) was determined by time-resolved infrared luminescence spectroscopy to be 1.5 ×106 M -1 sec-1 in CD3OD, smaller than previously reported values. Chemical reaction accounts for ca. 25% of kT.
