Chattopadhyay, Shital K.,Ghosh, Debalina,Neogi, Kaushik
, p. 1535 - 1543 (2007)
A new route to several medium ring heterocycle and carbocycle fused naphthalene derivatives of potential medicinal importance has been developed involving tandem applications of Claisen rearrangement and ring-closing diene metathesis as key steps. Copyright Taylor & Francis Group, LLC.
Diversity-oriented approach to biologically relevant molecular frameworks starting with β-naphthol and using the claisen rearrangement and olefin metathesis as key steps
Kotha, Sambasivarao,Mandai, Kalyaneswar,Tiwari, Arti,Mobin, Shaikh M.
, p. 8024 - 8038 (2006)
A diversity-oriented approach for the synthesis of various structurally different molecular frameworks from readily accessible and common precursors is described. A Claisen rearrangement followed by ring-closing metathesis or ethylene-promoted ring-closin
Naphthalene-based calixarenes: Unusual regiochemistry of a Friedel-Crafts alkylation
Shorthill, Berkeley J.,Glass, Timothy E.
, p. 577 - 579 (2001)
(Matrix presented) In the pursuit of naphthalene-based calixarenes, a Friedel-Crafts alkylation with unusual regiochemistry was observed. Treatment of carbinol 14 with catalytic triflic acid was expected to produced calixarenes of the class represented by 16. Instead, the major product was cyclic trimer 15, in which alkylation of each naphthalene ring occurred at the electronically deactivated position. The structure of compound 15 was assigned by 2-D NMR studies.
Non-linear, cata-Condensed, Polycyclic Aromatic Hydrocarbon Materials: A Generic Approach and Physical Properties
Haire, Barnaby T.,Heard, Kane W. J.,Little, Mark S.,Parry, Adam V. S.,Raftery, James,Quayle, Peter,Yeates, Stephen G.
supporting information, p. 9970 - 9974 (2015/07/07)
A generic approach to the regiospecific synthesis of halogenated polycyclic aromatics is made possible by the one- or two-directional benzannulation reactions of readily available (ortho-allylaryl)trichloroacetates (the "BHQ" reaction). Palladium-catalyse
An expedient synthesis of bis-fused benzofuran and a two-directional ring- closing metathesis for the synthesis of bisbenzoxepines and bisbenzoxocines
Majumdar, Krishna C.,Chattopadhyay, Buddhadeb,Chakravorty, Santanu
experimental part, p. 674 - 680 (2009/07/03)
Synthesis of bis-fused benzofuran derivatives by the implementation of palladium-mediated intramolecular cyclization is described. To our knowledge, this is the first report of the synthesis of bis-fused benzofuran by this protocol. Bisbenzoxepine and bis
The regiochemistry of the o-claisen rearrangement of bis-(alloxy)polycyclic aromatics
Majetich, George,Yu, Jianhua,Li, Yang,Allen, Scott H.
, p. 157 - 161 (2008/02/13)
The o-Claisen rearrangement of bis-(allyloxy) naphthalenes, anthracenes and phenanthrenes is regiospecific and is consistent with resonance theory and molecular orbital calculations.
Semi-rigid bis-phosphane ligands for metallamacrocycle formation
Armstrong, Susan K.,Cross, Ronald J.,Farrugia, Louis J.,Nichols, David A.,Perry, Alexis
, p. 141 - 151 (2007/10/03)
Efficient syntheses are described for the new bridging bis- phosphanes DPPN (4) and DPEN (5) built around the restricted rigidity of a 2,7-dialkoxynaphthalene backbone. These show marked preference for bridging pairs of metal atoms (Pt11, Mo0) to form metallamacrocycles or oligomers. Single-crystal X-ray structure determinations of four dimeric complexes with PtII and Mo0 are reported. The dimeric platinum complexes can be obtained as the kinetically favoured trans,trans products, which isomerise to the cis,cis forms in the presence of free ligand. cis,cis-[Pt2Cl4(DPEN)2] (12) shows marked hydroformylation catalytic activity.
THE CLAISEN REARRANGEMENT OF SOME ALLYL-β-NAPHTHYL ETHERS AND CYCLIZATION OF THE PRODUCTS
Prajer-Janczewska, Lidia,Wroblewski, Juliusz
, p. 1431 - 1437 (2007/10/02)
Some allyl-2-carboxy-3-hydroxy- as well as 2,3- and 2,7-diallyloxynaphtalenes were obtained.Respectively rearranged compounds were cyclized to naphthodihydrofuran rings.
