Different reactivities and selectivities are observed in water compared with those in organic solvents. In this article, such three examples are described. While ammonia was known not to react in metal-catalyzed allylic amination, palladium-catalyzed allylic amination using aqueous ammonia proceeded to afford primary amines in high yields. Second, allylboronates reacted with aldehydes in aqueous media to afford α-addition adducts exclusively in high yields with high diastereo- and enantioselectivities using Zn(OH)2with ligands as catalysts. Finally, it was found that catalytic use of In(0) was effective for the reactions of allylboronates with ketones in water.

: The reactions involving the formation of C-O bond using metal as a catalyst have emerged to be one of the most influential reactions for the synthesis of heterocycles in modern organic chemistry. Catalysis by metals offers diverse opportunities to invent new organic reactions with a promising range of selectivities such as chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. The methodologies used earlier for synthesis were less approachable to the organic chemist because of their high cost, highly specified instrumentation and inconvenient methods. For both stereoselective and regioselective formation of five-membered O-containing heterocycles, cyclic reactions that are metal and non-metal-catalyzed have known to be very efficient. The present review article covers the applications of metal and non-metal as a catalyst for the synthesis of five-membered O-containing heterocycles.
