Tan, Weiqiang; Zheng, Jifang; Chen, Le; Chai, Huining; Guan, Jing published an article in 2021. The article was titled 《Efficient one-pot synthesis of oxaperylenone derivatives promoted by propylphosphonic anhydride》, and you may find the article in Tetrahedron.Electric Literature of C7H12O3 The information in the text is summarized as follows:
Propylphosphonic anhydride (T3P)-mediated condensation and intramol. cyclization of 1-hydroxyanthraquinone with various active methylene acetates in the presence of Et3N was efficiently accomplished to afford oxaperylenone derivatives I [R1 = H, OMe; R2 = OEt, Ph, 3-BrC6H4, etc.]. The in situ generated propylphosphate derivatives were confirmed as reactive intermediates, which were produced by acylation from 1-hydroxyanthraquinone with T3P. The reaction mechanism was investigated theor. using d. functional theory, and a plausible reaction mechanism was proposed. The experimental process involved the reaction of Ethyl 3-oxopentanoate(cas: 4949-44-4Electric Literature of C7H12O3)
Ethyl 3-oxopentanoate(cas: 4949-44-4) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Electric Literature of C7H12O3
