Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 198544-60-4, is researched, SMILESS is O=C(OCC1C2=C(C3=C1C=CC=C3)C=CC=C2)N[C@H](CC(C)C)C(Cl)=O, Molecular C21H22ClNO3Journal, Article, Research Support, Non-U.S. Gov’t, Journal of Natural Products called Total Solid Phase Syntheses of the Quinazoline Alkaloids: Verrucines A and B and Anacine, Author is Wang, Haishan; Sim, Mui Mui, the main research direction is verrucine A B total solid phase synthesis; anacine total solid phase synthesis structure; quinazoline alkaloid total solid phase synthesis.HPLC of Formula: 198544-60-4.
The first total syntheses of verrucines A and B and anacine (revised structure) were accomplished on Sasrin resin. This work confirmed the structure of verrucine A and unambiguously showed verrucine B to be a derivative of D-phenylalanine and L-glutamine. The study also proved that anacine and its epimer are quinazoline alkaloids, not benzodiazepines as originally proposed. 1-Hydroxyverrucine B, derived from air oxidization of verrucine B, was also isolated and characterized.
