Synthesis and characterization of polyaromatic azine derivatives of (eta5-C5H5) Fe(CO)2 and (eta5-C9H7) Fe(CO)2

The synthesis and characterization of 14 monometallic derivatives of quinoline, quinoxaline, quinazoline and tetraazolo<1,5-A>quinoline and a bimetallic derivative of quinoxaline are reported. These species were prepared in 11 to 88% isolated yields by metathesis reactions between NaFp or NaFp? (where Fp = (eta5 – C5H5)Fe(CO)2 and Fp? = (eta5 – indenyl)Fe(CO)2 ) and the appropriate chlorine substituted polyaromatic azines. These reactions are highly regioselective and generally produce a single organometallic product having the organometallic substituent(s) bonded to the more highly activated azine ring. The structures of three representative examples were confirmed by their X-ray crystal structures, which are reported for the title complexes 4-[(eta5-cyclopentadienyl)irondicarbonyl]-7-chloroquinoline (C16H10ClFeNO2; a = 7.608(1)A, b = 12.006(1)A, c = 15.664(1)A, V = 1431A3; orthorhombic; P212121; Z =4), 2-[(eta5-cyclopentadienyl)irondicarbonyl]-3-chloroquinoxaline (C15H9ClFeN2O2; a = 15.291(3) A, b = 6.561(2) A, c = 14.541(4) A, beta = 106.891(21), V= 1395.9A3; monoclinic; P21/c; Z = 4), and 2-[(eta5-indenyl)irondicarbonyl]-3-chloroquinoxaline (C19H11ClFeN2O2; a = 19.131(2)A, b = 6.688(1)A, c = 13.515(2) A, beta= 101.569(11), V = 1694.1 A3; monoclinic; P21/c; Z = 4). The bimetallic quinoxaline derivative 2,3-[(C5H5)2Fe2(CO)4]-quinoxaline has orrto-substituted organometallic groups and the spectroscopic data suggest that it has an unusual structure in solution, perhaps involving bridging cyclopentadienyl and carbonyl ligands.

A phase-switch purification approach for the expedient removal of tagged reagents and scavengers following their application in organic synthesis

In this paper we wish to report on a variety of expedient chemical transformations and purifications achieved via a generic ‘catch and release’ methodology, based on a synthetically inert bipyridyl chelating tag that can be selectively captured with a resin-bound copper(II) species. Utilising this approach we are able to derive many of the same benefits associated with both solid phase synthesis and supported reagent methods. The Royal Society of Chemistry 2005.

Oligobisvelcraplex: Self-assembled linear oligomer by solvophobic pi-pi stacking interaction of bisvelcrands based on resorcin[4]arene

(Chemical Equation Presented) Bisvelcrand 3 based on resorcin[4]arene was obtained by a stepwise route, and the formation of oligobisvelcraplex 3 n by solvophobic pi-pi stacking interaction was observed. 1H NMR spectroscopic studies revealed that DeltaG ?pSeudorotation of oligobisvelcraplex 3n is 16.7 kcal mol-1 in C6D5NO2 solution. The pulsed field gradient spin-echo (PGSE) NMR experiment and VPO experiment showed that the number of aggregation (n) ranges from 7 to 10 in CHCl3 solution at 298 K. In high concentration, bisvelcrand 3 tends to form gels or fiber.

A novel approach to cyclin-dependent kinase 5/p25 inhibitors: A potential treatment for Alzheimer’s disease

Based on the earlier results of our in-house database and compound library, a series of novel clubbed thienyl triazoles was designed which may emerge as potential cdk5/p25 inhibitors, for the treatment of Alzheimer’s disease. A benign synthesis was planned so as to take an advantage of MAOS (Microwave Assisted Organic Synthesis) method. Evaluation of the SAR of this series has allowed the identification of compounds 4, 5, 7 and 8 from series I while 13, 14, 16 and 17 from series II as significant cdk5/p25 inhibitors and thus have potential as possible treatments for Alzheimer’s disease.
