Sagrera, Gabriel,Seoane, Gustavo
scheme or table, p. 2776 - 2786 (2010/10/19)
The synthesis of natural 3++,3?-binaringenin and four related biflavonoids was performed in good overall yield (15-35%) starting from readily available phloroglucinol and 4-hydroxy- or 4-methoxybenzaldehyde. Preliminary results indicate that some of these compounds have an interesting activity against S. aureus. Georg Thieme Verlag Stuttgart.
Acidic rearrangement of (benzyloxy)chalcones: A short synthesis of chamanetin
Sagrera, Gabriel,Seoane, Gustavo
scheme or table, p. 4190 - 4202 (2011/03/20)
Treatment of (benzyloxy)chalcones with trifluoroacetic acid in refluxing chloroform gave several new benzyl(hydroxy)flavanones in high yields and good regioselectivities. By using this procedure, we prepared the natural compound chamanetin in good yield from readily available reagents. Georg Thieme Verlag Stuttgart - New York.
BF3·OEt2 mediated regioselective deacetylation of polyacetoxyacetophenones and its application in the synthesis of natural products

, p. 4409 - 4415 (2008/12/21)
We have developed an efficient method to regioselectively deacetylate polyacetoxyacetophenones using BF3·OEt2 in excellent yields and demonstrated the application of the procedure in the synthesis of natural products.
Deacetylation of activated acetophenones with tin(IV) chloride
Hadjeri, Mohamed,Mariotte, Anne-Marie,Boumendjel, Ahcene
, p. 463 - 464 (2007/10/03)
Activated acetophenones were deacetylated by treatment with an excess of tin(IV) chloride in 1,2-dichloroethane.
Syntheses d'aryltetrahydropyrannyl ethers
Cottet, Francoise,Cottier, Louis,Descotes, Gerard,Srivastava, Rajendra Mohan
, p. 1481 - 1486 (2007/10/02)
L'addition de methoxyphenols 1 sur le dihydropyranne en milieu acide donne des produits C- et/ou O-tetrahydropyrannyles 3 et 4 dont le pourcentage est fonction du nombre de substituants methoxy et de la force du catalyseur acide.Les aryl tetrahydropyranny
PHOTO-FRIES REARRANGEMENT: REARRANGEMENT OF ACETOXYBENZENE DERIVATIVES
Sharma, Pavan Kumar,Khanna, Rajinder Nath
, p. 159 - 162 (2007/10/02)
Photo-Fries rearrangement of 1,4-diacetoxybenzene, 1,3,5-triacetoxybenzene, 1,2,3-triacetoxybenzene and 1,2,4-triacetoxybenzene gave the corresponding mono- and di-C-acetyl migrated products.
