Abstract We present a simple and efficient photocatalytic method for the transfer hydrogenation of alkenes alkynes using alcohol as hydrogen source inexpensive decatungstate photocatalyst. Our approach operates under mild, ambient conditions demonstrates broad substrate compatibility, accommodating alkyl, aryl, heteroatom-substituted alkynes. To our knowledge, this study represents first instance tungsten-based catalysts alkenes. Notably, decatungstate/alcohol catalytic system exhibits excellent chemoselectivity, enabling selective even in presence reactive groups like ketones carboxylic acids. These features highlight considerable potential practical sustainable applications organic synthesis.

Herein we first report a nickel-catalyzed asymmetric iterative 1,2-reduction of trisubstituted enones to cycloalkanols with two contiguous stereocenters in high yields excellent diastereo- and enantioselectivities (36 examples, up 98.5:1.5 er, >20:1 dr, TON = 500). The combined experimental computational mechanistic studies suggested energy changes during consecutive reduction processes provided range unique rationales that have not been disclosed hydrogenation-related studies.
