its considerable potential to streamline amine synthesis. State-of-the-art protocols for hydroaminomethylation of alkenes rely largely on transition-metal catalysis, enabling this transformation only under highly designed and controlled conditions. Here we report a broadly applicable, acid-mediated approach to the hydroaminomethylation of unactivated alkenes and alkynes. This methodology employs cheap

Provided is a process for producing an amine via a hydroaminomethylation reaction of a non-aromatic C-C double bond or C-C triple bond, said process comprising
a step of reacting a compound comprising a non-aromatic C-C double bond or C-C triple bond with a reactive component which is obtainable by combining an aminal with an acidic medium comprising trifluoroacetic acid,
wherein the aminal contains two amino groups independently selected from a secondary and a tertiary amino group that are linked by a methylene group, and at least one of the amino groups carries a hydrogen atom at a carbon atom bound in α-position to its nitrogen atom.

Design, Synthesis, and Biological Evaluation of Lysine Demethylase 5 C Degraders
Lysinedemethylase5C (KDM5C) controls epigenetic gene expression and is attracting great interest in the field of chemical epigenetics. KDM5C has emerged as a therapeutic target for anti‐prostate cancer agents, and recently we identified triazole 1 as an inhibitor of KDM5C. Compound 1 exhibited highly potent KDM5C‐inhibitory activity in in vitro enzyme assays, but did not show strong anticancer effects
