An article Diastereoselective Rhodium Catalyzed [4+2] Cycloisomerization of Allenes WOS:000641296000014 published article about HIGHLY ENANTIOSELECTIVE APPROACH; CYCLOADDITION; 4C+3C in [Li, Jun; Gilbertson, Scott R.] Univ Houston, Dept Chem, Houston, TX 77204 USA in 2021.0, Cited 18.0. The Name is 4-Methoxybenzaldehyde. Through research, I have a further understanding and discovery of 123-11-5. COA of Formula: C8H8O2
A diastereoselective [4 + 2] cycloisomerization of asymmetric allenyl dienes is reported. The asymmetric dienyl allenes are synthesized using the method reported by Ma. These substrates readily undergo diastereoselective intramolecular rhodium catalyzed [4 + 2] cycloisomerization analogous to thermal intramolecular Diels-Alder reactions. Overall, 29 examples are presented with tethers possessing nitrogen, oxygen, and carbon. Diastereoselectivities range from 99:1 to 90:10 in most examples.
