An efficient RhII‐catalyzed synthesis of functionalized α‐vinyl aldehydes with high E/Z
stereoselectivity was developed. The reaction mediates the cyclopropanation of …

Transition metal‐catalyzed C− S cross‐coupling has emerged as an important strategy to
furnish thioethers; however, the dominant utilization of noble metal catalysts as well as the …

A catalytic enantioselective construction of all‐carbon chiral quaternary centers through
reductive hydroxymethylation of 1, 1‐disubstituted allenes with CO2 has been developed. In …

The first catalytic asymmetric multiple vinylogous addition reactions initiated by Meinwald
rearrangement of vinyl epoxides were realized by employing chiral N, N′‐dioxide/ScIII …

A practical one-pot C–H formylation approach enabled by the relay catalysis of manganese
(I) and iron (III) has been developed. The effect of the directing group exhibited that 2 …

Construction of sterically congested all-carbon quaternary centers represents a formidable
challenge in synthetic chemistry. The method described herein provides direct and facile …

A Pd-catalyzed thiocarbonylative cyclization of N-(o-iodoaryl) acrylamides with easily
accessible thioformates has been developed. The reaction has a wide substrate scope with …

Carbon monoxide‐releasing molecules (CORMs) can offer a safer alternative to CO delivery
than the use of CO gas cylinders. Upon treatment with an amine base, S‐aryl thioformates …
