The Ru-catalyzed intramolecular [5+2] cycloaddition of cyclopropylenynes is investigated with respect to the regio- and diastereoselectivity as well as the functional group compatibility of the reaction. Evidence for the mechanism as occurring through a ruthenacyclopentene intermediate is elucidated from 1) the study of the diastereoselectivity of the cycloaddition; 2) the effect of variation of substituents

potent TIQ15-derived CXCR4 antagonists is reported. In this investigation, the TIQ15 side-chain was constrained to improve its drug properties. The cyclohexylamino congener 15a was found to be a potent CXCR4 inhibitor (IC50 = 33 nM in CXCL12-mediated Ca2+ flux) with enhanced stability in liver microsomes and reduced inhibition of CYP450 (2D6). The improved CXCR4 antagonist 15a has potential therapeutic

The synthesis of polyfunctionalized fused aromatic carbo- and heterocycles from aryl iodides and bromoenoates via a tandem palladium-catalyzed aromatic substitution intramolecularHeck sequence is reported. Using Pd(OAc)2 and tri-2-furylphosphine (TFP) in the presence of norbornene and Cs2CO3 in CH3CN at 85 °C gave a variety of functionalized bi- and tricyclic fused aromatic rings in good yield.

A simple synthetic route for novel acyclic phosphonatenucleosides is described. The characteristic cyclopropyl moiety 8 was constructed employing the Simmons-Smith reaction as key step starting from simple acyclic 2-butene-1,4-diol. The condensation of the mesylate 11 with natural nucleosidic bases (A,C,T,U) under nucleophilic substitution conditions (K2CO3, 18-Crown-6, DMF) and hydrolysis afforded
