Enantioselectivity in Transition Metal Catalyzed Propargylic Substitution Reactions: A Theoretical Perspective

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
Recent theoretical efforts to elucidate the origin of enantioselectivity in transition metal‐catalyzed propargylic substitution reactions are highlighted in this review. ABSTRACT In recent years, asymmetric catalytic propargylic substitution reactions have undergone remarkable development, enabling the construction of chiral carbon centers adjacent to ...

Triptindane‐9,10,11‐triol: Threefold Hydride Transfer from Lithium Aluminum Hydride as the Key Step to C3‐Symmetrically Trifunctionalized Tribenzo[3.3.3]propellanes

European Journal of Organic Chemistry, Volume 29, Issue 15, 22 April 2026.
Threefold reduction of 9,10,11‐triptindanetrione with LiAlH4 or NaBH4 yields exclusively the C3‐symmetric triol, suggesting an intracomplex (“rolling”) mechanism. However, use of LiAlH4/LiAlD4 (1 : 1) reveals a preceding hydride exchange. Mechanistic implications are discussed including the reduction of the related diketone.

Chemoselectivity and Enantioselectivity in the Conjugate Reduction of Cinnamate Esters and a Tandem Conjugate Reduction‐Ester Hydrogenation Using Manganese Catalysts

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
An improved synthesis of a manganese catalyst used for hydrogenation of ketones, esters and imines is reported. The catalyst has now been found to effect tandem conjugate reduction‐ester hydrogenations with very low amounts of allylic alcohol by‐products.
