phorylnitrone and N-arylacrylamides in good yields. cis- and trans-isoxazolidine phosphonates obtained herein were evaluated for activity against a broad range of DNA and RNA viruses. None of the compounds were endowed with antiviral activity at subtoxic concentrations. Isoxazolidines having phenyl substituted with halogen (Ar = 2-F-C6H4; 3-Br-C6H4; and 4-Br-C6H4) have been found to inhibit proliferation

An unexpected cascade reaction is developed for the construction of functionalized 3-bis(indol-3-yl)methylquinoline-2(1H)-ones. Three C–C bonds and one ring are created in one pot triggered by Pd-catalyzed C-3 alkenylation of indole with 2-acyl-N-acrylaniline derivatives. A series of complex and specific quinoline-2(1H)-ones were produced, most of them showed significant α-glucosidase inhibitory activities

The present invention provides a hot melt acrylic pressure sensitive adhesive (PSA) comprising an acrylic polymer having units derived from one or more C1-C20 alkyl esters of acrylic or methacrylic acid and units derived from one or more vinyl esters corresponding to the formula:
wherein R1, R2 and R3 each independently represent an alkyl group and the total number of carbon atoms in the vinyl ester is from 7 to 18. The PSA is particularly suitable for sticking objects to a low surface energy substrate.
The present invention relates to a radiation crosslinkable pressure sensitive adhesive precursor comprising:
a) an acrylate base polymer;
b) a co-polymerized type (II) photocrosslinker, in a amount greater than 0.05 parts by weight per 100 parts by weight of acrylate base polymer;
c) a co-polymerized hydrogen-donating monomer; and
d) a tackifying resin, in an amount greater than 40 parts by weight per 100 parts by weight of acrylate base polymer.
The present invention is also directed to a method of preparing a radiation crosslinked pressure sensitive adhesive.
