Khumalo, MR; Maddila, SN; Maddila, S; Jonnalagadda, SB in [Khumalo, Mandlenkosi Robert; Maddila, Surya Narayana; Maddila, Suresh; Jonnalagadda, Sreekantha B.] Univ KwaZulu Natal, Sch Chem & Phys, Westville Campus,Chiltern Hills, ZA-4000 Durban, South Africa published A multicomponent, facile and catalyst-free microwave-assisted protocol for the synthesis of pyrazolo-[3,4-b]-quinolines under green conditions in 2019.0, Cited 41.0. SDS of cas: 500-22-1. The Name is 3-Pyridinecarboxaldehyde. Through research, I have a further understanding and discovery of 500-22-1.
A facile, swift and ecofriendly microwave-assisted multi-component/one-pot protocol is designed for the synthesis of novel pyrazolo-[3,4-b]-quinolines at ambient temperature in aqueous ethanol as a reaction medium. The 18 novel pyrazolo-[3,4-b]-quinoline derivatives were synthesized by fusion of chosen aryl aldehyde, dimedone and 5-amino-3-methyl-1-phenylpyrazole in excellent yields (91-98%). All the molecular structures were confirmed by H-1-NMR, N-15-NMR, C-13-NMR, and HRMS data analysis. Operational simplicity, easy handling, one-step simple workup procedure, mild reaction conditions, short reaction time (<= 10 min), high selectivity and no by-product formation are the striking features of the protocol. SDS of cas: 500-22-1. Welcome to talk about 500-22-1, If you have any questions, you can contact Khumalo, MR; Maddila, SN; Maddila, S; Jonnalagadda, SB or send Email.
