In this article, a selective formal anti-Markovnikov hydroamination of allyl alcohols is presented. It enables the versatile synthesis of valuable γ-amino alcohol buildingblocks. A phosphine-free Earth’s abundant manganese(I) complex catalyzed the reaction under hydrogen-borrowing conditions. A vast range of aliphatic, aromatic amines, drug molecules, and naturalproduct derivatives underwent successful

synthesis of β-alkylated secondary alcohols via the regioselective ring-opening of epoxides with feedstock primaryalcohols. The reaction utilized alcohol as the carbon source and the terminal reductant. Kinetic and labeling experiments elucidate the hydrogentransfercatalysis that operates via tandem Markovnikov selective transferhydrogenation of terminal epoxides and hydrogen transfer-mediated cross-coupling
