The synthesis, characterization and catalytic evaluation of a series of NHC-Ni(II) complexes 1-Ni (-Me), 2-Ni (-nBu) and 3-Ni (-Bn) bearing a phthalimide fragment and a cyclopentadienyl (Cp) ligand is reported. The complexes were evaluated in C[sbnd]S couplings of iodobenzene and a range of thiols. The reactions were carried out using a catalyst loading of 5 mol % in DMF during 0.5?19 h. Being complex 2-Ni the one exhibiting the best activity for these transformations yielding up to 96% of products in 0.5 h.

Synthesis of nitrogen and sulfur macrocycles with cis exogenous oxygen and sulfur donor atoms

A series of new N4 and N8 macrocycles has been prepared, that includes cis-exogenous O2, S2 and S/O atoms to allow chelation to a metal external to the macrocyclic ring. We found that thioamide units within the macrocycles were unstable to attack by secondary amines and thus alkylated precursors containing only tertiary amines could lead to exogenous-S2 macrocycles. Cyclisation of alkylated tetraamine precursors with dimethyloxalate or dithiooxamide led to both N4 and N8 macrocycles via 1 + 1 and 2 + 2 cyclisation reactions with exogenous-O2 or S2 respectively. Alkylation of preformed exogenous-O2 macrocycles was explored and led to alkyl substitution at the secondary amine nitrogens in the ring, however synthesis of these species was overall lower yielding than cyclisation using alkylated tetraamine precursors. Thionation of an exo-O2 macrocycle using an analogue of Lawesson’s Reagent led to formation of the analogous exogenous-S2 and exogenous-O,S macrocycles. Related S2N2 macrocycles with exogenous-O2: were prepared by a cyclisation route but could not be isolated free of larger ring analogues. The Royal Society of Chemistry 2005.

Synthesis and biological evaluation of 2,4-diaminoquinazoline derivatives as novel heat shock protein 90 inhibitors

Novel 2,4-diaminoquinazoline derivatives originating from a virtual screening approach were designed, synthesized and their biological activities as heat shock protein 90 (Hsp90) inhibitors were evaluated. The prepared compounds exhibited significant anti-proliferative activities against DU-145, HT-29, HCT-116, A375P and MCF-7 cancer cell lines. The selected compounds were tested against Her2, a client protein of Hsp90, and showed significant reduction in Her2 protein expression. Compound 6b was found the most potent, reduced Her2 protein expression levels and induced Hsp70 protein expression levels significantly.

Hair dye compositions and new compounds useful therein

Novel compounds of the general formula STR1 wherein Z represents a substituted lower alkyl radical; each of R1 and R2 is hydrogen atom, a lower alkyl or a substituted lower alkyl identical with or different from Z and the functional groups NO2 and NR1 R2 can occupy all ring positions in relation to OZ, with the exception that if Z is beta-hydroxyethyl, –NO2 is in the 4 position and –N(R1)(R2) is in the 2 position then either R1 or R2 is other than hydrogen. The novel compounds are for dyeing human hair in a variety of yellow shades. The compounds of formula (I) may be used as aqueous or water-alcohol solutions to form dye compositions for dyeing human hair.

The Reaction of Lithium Phenylacetylide and Phenyllithium with N-(omega-Bromoalkyl)phthalimides

Lithium phenylacetylide reacted with short-chain N-(omega-bromoalkyl)phathalimides 1b and 1c to give tricyclic products 2b and 2c in moderate yields.Likewise, tricyclic products 3a-c were obtained when short-chain imides 1a-c were treated with phenyllithium.When longer-chain imides 1d-f in this series were treated with lithium phenylacetylide only tertiary alcohols 4d-f could be isolated.Partial hydrogenation of 2b and 2c yielded the corresponding alkenes 5b and 5c, products which corroborated the structural assignment of 2b and 2c.
