Solution and solid-state characterization of a dicopper receptor for large substrates
Davidson, Greg J.E.,Baer, Andrew J.,Cote, Adrien P.,Taylor, Nicholas J.,Hanan, Garry S.,Tanaka, Yasutaka,Watanabe, Masashi
, p. 496 - 498 (2002)
Ligand 2 contains two metal-binding domains separated by a rigid spacer and assembles into a dicopper receptor with a large central cavity with no evidence of catenation.
Synthesis, complexation studies and biological applications of some novel stilbenophanes, indolophanes and bisindolostilbenophanes via McMurry coupling
Rajakumar, Perumal,Gayatri Swaroop, Merikapudi,Jayavelu,Murugesan
, p. 12041 - 12050 (2007/10/03)
Various types of stilbenophanes, indolophanes and bisindolostilbenophanes were synthesized by intra-, inter- and tandem intra-, intermolecular McMurry coupling. Some of the indolophanes and bisindolostilbenophanes exhibited significant activity against th
The use of McMurry coupling for the synthesis of indolophanes and cis-stilbenophanes

, p. 6165 - 6167 (2007/10/03)
Treatment of 2equiv of indole-3-aldehyde with o, m, p-xylyl, 2,5-dimethoxy-p-xylyl dibromides and 4,4′-bis(bromomethyl)-1,1′- biphenyl gave the bisalkylated products, which underwent McMurry coupling with low valent titanium to give indolophanes. Various cis-stilbenophanes with m-terphenyl building blocks were also synthesized by application of the McMurry coupling technique.
Meta-terphenyls as building blocks for benzimidazolophanes
Rajakumar, Perumal,Srisailas, Muthialu
, p. 5323 - 5326 (2007/10/03)
Coupling of the dibromide 4 and the tetrabromide 6 with benzimidazole gave the benzimidazolophanes 1 and 2 respectively.
Synthesis of cyclophanes with intra-annular functionality and cage structure
Kannan, Arunachalam,Rajakumar, Perumal,Kabaleeswaran,Rajan
, p. 5090 - 5102 (2007/10/03)
Cyclophanes of the type 1 and 2, with large cavity sizes, have been synthesized from the corresponding dichloride 8 or 8a and o-xylene-α,α′-dithiol (9), p-xylene-α,α′-dithiol (10), or m-terphenyldithiol (11). Similarly, cyclophanes of the type 3 with intr

2′-Substituted meta-terphenyls as building blocks for cyclophanes with intra-annular functionality
Hart, Harold,Rajakumar, Perumal
, p. 1313 - 1336 (2007/10/02)
2′-Substituted m-terphenyls containing chloromethyl and/or thiomethyl groups at the 4,4″ or 3,3″ positions are used as building blocks for cyclophanes with intra-annular functionality. Syntheses are short and yields are good. The methodology, capable of w

Banfi, Stefano,Montanari, Fernando,Pozzi, Gianluca,Quici, Silvio
, p. 9025 - 9036 (2007/10/02)
The first example of dimeric Mn(III)-tetraarylporphyrins able to catalyze olefin epoxidation is reported.In the presence of one equivalent of lipophilic bidentate ligand 3 the efficiency of some of these catalysts is among the highest reported to now in 3
Synthesis of Dithiacyclophanes with Large Molecular Cavity
Rajakumar, Perumal,Kannan, Arunachalam
, p. 4407 - 4410 (2007/10/02)
Coupling of the dichlorides 9 and 10 with xylenedithiols and m-terphenyldithiol under high dilution technique in presence of KOH in benzene-ethanol afforded the cyclophanes of the class 1 and 2.
