SMALL MOLECULE INHIBITORS OF PI3-KINASE SIGNALING

Provided are certain 1,2,3-triazole and 1,2,3-triazole dimer analogs of DM-PIT-1 which are second-generation selective non-phosphoinositide small molecule inhibitors of phosphatidylinositol-3,4,5-trisphosphate (PIP3), including 1,2,3-triazoles represented by formula (I) where: Ar represents aryl or heteroaryl; X represents O or S; each of Ra, Rb, Rc, and Rd independently represents hydrogen, halogen, C1-C10alkyl, -OH, -CF3, aryl, amino, or nitro; and Ar is optionally substituted with one or more substituents independently selected from the group consisting of halogen, C1-Cioalkyl, -OH, -CF3, amino, and nitro. Also provided are pharmaceutical compositions comprising compounds of the invention and a pharmaceutical carrier. Also provided are methods of inhibiting PIP3-mediated signaling in a cell and treating cancer using compounds of the invention.

Palladium-catalyzed silastannation of secondary propargylic alcohols and their derivatives

A series of terminal propargylic alcohols and their derivatives were subjected to Pd-catalyzed silastannation. In all reactions, complete regio- and stereoselectivities were observed with the tributyltin moiety exclusively adding to the internal carbon of the triple bond in a cis fashion, including the first example of a diyne bis-silastannation. Silastannation reaction products could sequentially be protiodesilylated or iododestannylated, thus providing synthetic routes to 1,1-gem-disubstituted alkenylstannanes and iodides, respectively.

Synthesis of 2-Aryl-(2-R)-arsenines by Cyclohexadienol -> Arsabenzene Rearrangement

KOH/crown-6 phase-transfer catalyzed addition of arylarsines (phenylarsine, p-tolylarsine) to the (3-R)-3-methoxy-1,4-pentadiynes 13 yields the cis/trans isomeric 1-aryl-1,4-dihydro-(4-R)-4-methoxyarsenines, the 1H-NMR- and 13C-NMR spectra of which ar
