of this study was the synthesis and lead structure selection of a best anti-leukemic agent from a library of aza-podophyllotoxin analogues (APTs). To this end, we report a scalable, modified multicomponent reaction using a "sacrificial" aniline partner as a more general route to rapidly construct the pivotal library of 50 APT analogues. Our preliminary structure activity relationship studies for anti-leukemic
Novel perfluorophenyl phosphonate analogues of phenylglycine and homophenylalanine were prepared in good to excellent yields, and subjected to solid state characterization by single-crystal X-ray diffraction analysis, and to investigations with the use of DFT methods. The α-aminophosphonates have a big potential for biological activity, and through SNAr reactions may give an entrance to further structurally

Iodine-promoted imino-Diels–Alder reaction of fluorinated imine with enol ether: synthesis of 2-perfluorophenyl tetrahydroquinoline derivatives
Iodine was used to catalyze the hetero-Diels-Aider reaction of pentafluorobenzylidineaniline (C6F5CH=NAr 1) with enol ethers to afford the corresponding tetrahydroquinolines derivatives as a mixture of cis/trans stereoisomers in moderate yields. These products could also be prepared by onepot, three-component reaction of pentafluorophenylaldehyde, anilines, and enol ethers under the same reaction condition. Mild and neutral reaction conditions, facile experimental procedure, and low price of iodine should make this method attractive for practical synthesis of many fluorinated tetrahydroquinoline derivatives.
