Mphahlele, Malose J.,Olomola, Temitope O.
, p. 3431 - 3442 (2019)
Tandem palladium-catalyzed Sonogashira cross-coupling and heteroannulation of 3-bromo-2,4-dihydroxy-5-iodoacetophenone with arylacetylenes followed by the base-mediated Claisen-Schmidt aldol condensation of the intermediate 5-acetyl-2-aryl-7-bromo-6-hydro
SYTHESIS OF ISOEUPARIN, A BENZOFURAN EXTRACTIVE OF TAGETES PATULA
Burke, John M.,Scannell, Ralph T.,Stevenson, Robert
, p. 1248 - 1249 (1986)
The structure of isoeuparin, a constituent isolated from seedlings of Tagetes patula, is confirmed by a short synthesis, involving reaction of cuprous isopropenylacetylide with 2,4-dihydroxy-3-iodoacetophenone.Key Word Index - Tagetes patula; Compositae;
Total synthesis confirms laetirobin as a formal diels-alder adduct
Simon, Oliver,Reux, Bastien,La Clair, James J.,Lear, Martin J.
experimental part, p. 342 - 351 (2010/07/13)
Laetirobin, isolated from a parasitic fungus host-plant relationship, was synthesized in six practical steps with an overall yield of 12% from commercially available 2,4-dihydroxyacetophenone. Because the product is a pseudosymmetric tetramer of benzo[b]-
A practical iodination of aromatic compounds by using iodine and iodic acid
Shinde, Avinash T.,Zangade, Sainath B.,Chavan, Shivaji B.,Vibhute, Archana Y.,Nalwar, Yogesh S.,Vibhute, Yeshwant B.
experimental part, p. 3506 - 3513 (2011/02/22)
This article describes simple and efficient method for the iodination of different aromatic amines, hydroxy aromatic aldehydes, hydroxy acetophenones and phenols using iodine and iodic acid in ethanol as a solvent. Notable advantages include mild reaction condition, no need of catalyst, short reaction time, simple practical procedure, giving excellent yield of the product. Copyright Taylor & Francis Group, LLC.
A short synthetic route to benzofurans. syntheses of naturally occurring euparin and related compounds
Sogawa, Akihiro,Tsukayama, Masao,Nozaki, Hiroshi,Nakayama, Mitsuru
, p. 101 - 111 (2007/10/02)
Euparin (4a) and related benzofurans (4b-e, g) were synthesized by conversion of the corresponding o-(3-hydroxy-3-methylbutynyl)phenyl tosylates (2) in the presence of base into the 2-(1-hydroxy-1-methylethyl)benzofurans (3), followed by dehydration in hi
Syntheses of the Natural Dibenzofuran, Ruscodibenzofuran
Scannell, Ralph T.,Stevenson, Robert
, p. 2927 - 2932 (2007/10/02)
Short syntheses of the natural dibenzofuran, ruscodibenzofuran (1) from readily available phenols are described.The key step involve initial formation of a 2-isopropenylbenzofuran by reaction of an ortho-halogenophenol with cuprous isopropenylacetylide fo
