A Short, Atom-Economical Entry to Tetrahydroxanthenones
Lesch, Bernhard,Braese, Stefan
, p. 115 - 118 (2004)
A reaction that takes to water: The domino Michael addition/aldol condensation of salicylic aldehydes like 1 as the nucleophile and 2-cyclohexen-1-one (2) as the Michael acceptor provides 2,3,4,4a-tetrahydroxanthen-1-ones such as 3 in good yields. DABCO =
Synthesis and antiviral activity of 1-hydroxy-2-(2-hydroxyphenyl)imidazoles against vaccinia virus
Nikitina,Bormotov,Shishkina,Tikhonov, A. Ya.,Perevalov
, p. 634 - 637 (2019)
2-(2-Hydroxyplienyl)imidazole derivatives were synthesized and tested for antiviral activity against vaccinia virus in Vero cell culture. 1-Methylimidazole 3-oxides, 1-methoxyimidazoles, and 1H-imidazoles showed no activity, whereas some 1-hydroxyimidazole derivatives hold promise, exhibiting antiviral activity and weak cytotoxicity.
Enantioselective Reduction of Ketones and Synthesis of 2-Methyl-2,3-dihydro-1-benzofuran Catalyzed by Chiral Spiroborate Ester

Abstract: Asymmetric reduction of homobenzylic ketones was achieved through the use of chiral spiroborate ester catalyst. The catalyst is applicable for both analytical and industrial purposes since it is not sensitive to air and moisture. A rapid synthetic route has been developed for the preparation of (S)-2-methyl-2,3-dihydro-1-benzofuran via enantioselective reduction of homobenzylic ketone in the presence of a chiral spiroborate catalyst as the key step.
