Recently I am researching about HIGHLY ENANTIOSELECTIVE APPROACH; CYCLOADDITION; 4C+3C, Saw an article supported by the M.D. Anderson Foundation; University of Houston. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Li, J; Gilbertson, SR. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde. Category: indole-building-block
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.
