<p>In nature, plants convert solar energy into chemical energy via water oxidation.1,2 Inspired by natural photosynthesis, artificial photosynthesis has been gaining increasing interest in the field of sustainability/green science and technology as a non-natural and thermodynamically endergonic (ΔG° &gt; 0, uphill) solar-energy-driven reaction that uses water as an electron donor and source material.3,4 Among the artificial-photosynthesis processes, inorganic-synthesis reactions via water oxidation, including water splitting and CO2-to-fuel conversion, have been attracting much attention.5,6 In contrast, the synthesis of high-value functionalized organic compounds via artificial photosynthesis, which we have termed “artificial photosynthesis directed toward organic synthesis” (APOS),7 remains a great challenge. Herein, we report a pioneering example of APOS. The carbohydroxylation of C=C double bonds is accomplished via a three-component coupling with H2 evolution, where carbon groups activated via C–H bond scission and a hydroxy group derived from water are incorporated into the products. In these reactions, water also provides the hydroxyl radical for oxidation and electrons for the H2 evolution reaction. This uphill transformation is induced by dual functions of semiconductor photocatalysts, i.e., silver-loaded titanium dioxide (Ag/TiO2)8 and rhodium–chromium–cobalt-loaded aluminum-doped strontium titanate (RhCrCo/SrTiO3:Al),9–11 under simulated solar light. The present APOS protocol enables the rapid and creative construction of useful organic frameworks for drug synthesis.</p>

<jats:p>In this account, we review our research over the last decade on metal-loaded semiconductor-photocatalyzed organic transformations using alcohols. Different from many reactions using alcohols as mere sacrificial electron donors, our study has demonstrated alcohols as useful organic building blocks incorporated into value-added products. Besides such recollections of previous results, we briefly introduce our ongoing project involving photocatalytic C–C bond-forming reactions via the C–C bond scission of tertiary alcohols.
