Abstract
A concise method for the synthesis of cis-(8b,14a)-hexahydro-14H-dibenzo[f,h]oxazolo[3,2-b]isoquinolin-14-ones 2 via photo-induced 3-([1,1'-biphenyl]-2-yl)-1-(2-hydroxyethyl)pyridin-2(1H)-ones 1 was developed. Irradiation of 1 in the solution of toluene with a 313 nm UV light in the presence of HCl gave cis-(8b,14a)-9a-α-hexahydro-14H-dibenzo[f,h]oxazolo[3,2-b]isoquinoli n-14-ones and cis-(8b,14a)-9a-β-hexahydro-14H-dibenzo[f,h]oxazolo[3,2-b]isoquinolin-14-ones 2 (2-α and 2-β) in good yields. The protocol simultaneously constructs dearomatized phenanthrene ring and oxindolizidinones ring by photo cascade reaction to achieve high bonding efficiency and high atomic efficiency. Additionally, the antitumor activities of 2 was evaluated and compounds 2b-α, 2b-β, 2j-β and 2 k-α showed similar or better activity compared to the cisplatin against tumor cell lines of Leukemia HL-60, lung cancer A594, liver cancer SMMC-7721 and breast cancer MDA-MB-231.

Abstract
To study the influence of the substituent at the N-10 position on antiviral activity, the chiral quaternary ammonium salt derivatives of R- and S-tylophorine were designed, synthesized, and evaluated for antiviral activity against tobacco mosaic virus (TMV). The bioassay results indicated that most of the designed structural analogues showed good in vivo anti-TMV activity, among which propargyl quaternary ammonium salt compound S-7b showed the best anti-TMV activities (80.5%, 77.6%, 76.6%, 82.1%) at 500 μg/mL both in vitro and in vivo in the laboratory. In the field trials of antiviral efficacy against TMV, S-7b as well exhibited better activities than control plant virus inhibitors. The stability of compound S-7b was obviously increased, and its solubility was more than 500-times higher than that of S-tylophorine. Therefore, chiral quaternary ammonium salt S-7b was expected to be developed as a promising candidate as an inhibitor of plant virus.
