Saturated oxygen-containing heterocycles are present in numerous natural products and biologically active compounds. While the oxa-Pictet–Spengler reaction conventionally serves as a traditional synthetic strategy for preparing arene-fused tetrahydropyrans (THPs), existing methods typically involve harsh conditions. Disclosed herein is the development of a mild photocatalytically triggered oxa-Pictet–Spengler
