Cationic Pd(II)-Catalyzed Highly Enantioselective Arylative Cyclization of Alkyne-Tethered Enals or Enones Initiated by Carbopalladation of Alkynes with Arylboronic Acids
摘要:
Cationic Pd(II)-catalyzed enantioselective arylative cyclization of alkyne-tethered enals or enones initiated by carbopalladation of alkynes was developed without the necessity of a redox system.

The rhodium‐catalysedcarbonylation of 1,6‐enynes possessing an electron‐deficient alkenyl moiety in an alcohol reagent in the presence of a rhodiumcomplex proceeded stereo‐ and chemoselectively to afford exocyclic α,β‐enoates.
