Recently I am researching about ASYMMETRIC CONJUGATE ADDITION; CARBOXYLIC-ACIDS; FACILE ACCESS; QUATERNARY; DIHYDRONAPHTHOQUINONES; BENZOFURAN-2(3H)-ONES; BENZOFURAN-2-ONES; STEREOCENTERS; DERIVATIVES; CYCLIZATION, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21390400]. Recommanded Product: 87-41-2. Published in SCIENCE PRESS in BEIJING ,Authors: Wang, J; Li, X; Cheng, JP. The CAS is 87-41-2. Through research, I have a further understanding and discovery of Isobenzofuran-1(3H)-one
A highly diastereoselective and enantioselective Michael addition/desymmetrization reaction of maleimides with prochiral 3- substituted phthalides catalyzed by quinine-derived bifunctional thiourea was realized. A broad range of the 3,3-disubstituted phthalides bearing vicinal quaternary-tertiary stereogenic centers were synthesized in moderate to good yields (up to 96%) with high diastereoselectivities (up to >19:1 dr) and enantioselectivities (up to 96:4 er).
Recommanded Product: 87-41-2. About Isobenzofuran-1(3H)-one, If you have any questions, you can contact Wang, J; Li, X; Cheng, JP or concate me.
