I found the field of Chemistry very interesting. Saw the article Cu(i)-Catalyzed asymmetric exo-selective synthesis of substituted pyrrolidines via a 1,3-dipolar cycloaddition reaction published in 2021.0. COA of Formula: C5H8N2, Reprint Addresses Singh, VK (corresponding author), Indian Inst Technol Kanpur, Dept Chem, Kanpur 208016, Uttar Pradesh, India.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole
An (R)-DM-BINAP/Cu(CH3CN)(4)BF4 complex catalyzed exo-selective asymmetric 1,3-dipolar cycloaddition (1,3-DCA) reaction of imino esters with alpha,beta-unsaturated pyrazoleamides has been developed. A series of highly functionalized pyrrolidines with multiple stereogenic centers were obtained with good yields and diastereoselectivities and excellent enantioselectivities (up to 99% ee).
COA of Formula: C5H8N2. Welcome to talk about 67-51-6, If you have any questions, you can contact Biswas, RG; Ray, SK; Kannaujiya, VK; Unhale, RA; Singh, VK or send Email.
