DOCTORAL RESEARCH SUMMARY

1. Construction of Polycyclic Indole Derivatives via Multiple Aryne Reactions with Azaheptafulvenes

(Org. Lett. 2018, 20, 644 647.)

An efficient [8+2]/aryl ene tandem reaction between azaheptafulvenes and arynes has been developed, leading to the formation of cyclohepta[b]indoles in a single step with good yield. In addition, employment of excess arynes provides a [8+2]/aryl ene /[6+2] tandem reaction to synthesize polycyclic oxacyclohepta[b]indoles. This is the first time that azaheptafulvenes have been employed in tandem reactions with arynes.

2. Synthesis and anticancer activity evaluation of novel azacalix[2] arene[2] pyrimidines

(Eur. J. Med. Chem. 2018, 151, 214–225.)

A series of novel azacalix[2]arene[2]pyrimidines were synthesized, and evaluated for their antiproliferative activities against A549, MCF7, SH-SY5Y and CNE human cancer cell lines in vitro by using the CCK-8 assay. A number of compounds showed low micromolar antiproliferative activities against MCF7 cell line. Compound 4j, containing a pyrrolidine moiety, exhibited the strongest inhibitory activity with an IC50 value of 0.58 μM. Furthermore, breast cancer cells were used to explore the inhibition mechanism of these azacalix[2]arene[2]pyrimidines. The results suggested these compounds were involved in inducing cell apoptosis via up-regulation of caspase-3 and caspase-9 protein expression, and the cell cycle was arrested at the S phase. Our reports here represent the first studies on the biological activities of azacalix[2]arene[2]pyrimidines. 3. Tandem Diels Alder/Oxidation Aromatization Reaction of 2-Styrylchromones with Arynes: Construction of Benzo[c]xanthones

Org. Biomol. Chem. 2018 ( Under review)

Transition-metal-free Diels-Alder and tandem Diels Alder/oxidation aromatization reaction of 2- styrylchromones with arynes have been demonstrated under mild reaction conditions with a wide range of substrates. This efficient protocol allows rapid access to both dihydro benzo[c]xanthone and benzo[c]xanthone derivatives selectively by simply changing the atmosphere of the reaction. 4. Design, synthesis and antiproliferative activity of novel N-sulfonyl aryl-1,2,4- triazole derivitives

Eur. J. Med. Chem. (Manuscript under preparation)

A series of novel N-sulfonyl aryl-1,2,4-triazole derivitives were designed, synthesized and evaluated for their antiproliferative activity against five selected cancer cell lines (against A549, MCF7, U266, MM1S and MV4-11). Most of the synthesized compounds exhibited moderate to good activity against all the cancer cell lines selected. The N-sulfonyl aryl-1,2,4-triazole derivatives 18b and 18e were the most active compounds against MM1S and MV4-11 cells, respectively Particularly, compound 18a showed the most excellent antiproliferative activity with an IC50 value of 0.19 μM against MV4- 11cancer cells. Moreover, SAR conclusion based on study clearly identified a structural feature that should be retained for good activity and also a moiety that can tolerate various modifications and may find potential medicinal applications with further structural modulations and biological studies. 5. Asymmetric Mannich reaction of α-Diazocarbonyl compounds and N-sulfonyl Cyclic Ketimines Catalyzed by Complexes Generated from Chiral and Achiral Phosphines with Gold(I)

(Org. Biomol. Chem. 2018, 16, 2923–2931.)

An unprecedented Lewis acidic gold(I)-complex generated from chiral and achiral phosphines has been developed for the Mannich reaction of α-diazocarbonyl compounds and N-sulfonyl cyclic ketimines. A series of chiral β-amino-α-diazoesters bearing a quaternary stereocenter were obtained in high yields with good enantioselectivities. In addition, the products could be converted to promising bioactive spirosuccinimide. Furthermore, Operando IR, NMR and control experiments were carried out to gain insight into the mechanism.

7. Total Syntheses of cyclic depsipeptide ilamycins B1

(in progress)

The first total synthesis of the potent antimycobacterial cyclic depsipeptide natural product ilamycin B1 is described. Key features of our synthesis include the concise preparation of a linear cyclization precursor that consists of only L-amino acid residues (L-N-methyl leucine, L-tryptophan derivative, L-2-amino-tran&hexenoic acid, L- leucine, LN-methyl leucine, L-alanine and L-3-nitrotyrosine) and its macrolactamization from a bent conformation.The cyclic core of the ilamycins was shown to be responsible for the excellent antituberculosis activity
