An article Direct Enantioselective and Regioselective Alkylation of beta,gamma-Unsaturated Carboxylic Acids with Chiral Lithium Amides as Traceless Auxiliaries WOS:000461843900082 published article about ASYMMETRIC ALKYLATION; ARYLACETIC ACIDS; PSEUDOEPHEDRINE; OXAZOLIDINONES; DILITHIUM; CARBON in [Yu, Kai; Miao, Bukeyan; Wang, Wenqi; Zakarian, Armen] Univ Calif Santa Barbara, Dept Chem & Biochem, Santa Barbara, CA 93106 USA; [Miao, Bukeyan] Univ Michigan, Sch Med, Dept Internal Med Hematol Oncol, 930 N Univ Ave, Ann Arbor, MI 48109 USA in 2019.0, Cited 33.0. SDS of cas: 93-02-7. The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7
Efficient asymmetric alkylation of beta,gamma-unsaturated carboxylic acids without prior functionalization is enabled by chiral lithium amides. Enantioselectivity is imparted by a putative mixed lithium amide-enediolate aggregate that acts a traceless auxiliary formed in situ, allowing for a direct asymmetric alkylation and a simple recovery of the chiral reagent.
SDS of cas: 93-02-7. About 2,5-Dimethoxybenzaldehyde, If you have any questions, you can contact Yu, K; Miao, B; Wang, WQ; Zakarian, A or concate me.
