Au-catalyzed intramolecular hydroalkoxylation of gem-difluorinated alkynols
Hamel, Jean-Denys,Paquin, Jean-Fran?ois
, p. 11 - 23 (2018)
The intramolecular hydroalkoxylation of gem-difluorinated alkynols was found possible under Au catalysis, allowing for the preparation of a series of fluorinated heterocycles. The nature of the solvent was found to be especially critical in the cyclizatio

, p. 5383 - 5394 (2007/10/02)
Eleven new chiral macrocycles (1-11, see Figure 1) of the pyridino-18-crown-6 type have been prepared.Nine diazapyridino-crown ligands contain two amide (1, R = benzyl; 4, R = phenyl), two N-methylamide (7, R = phenyl), two thionoamide (2, R = benzyl; 5,
Propoxybenzene derivatives and process for preparing the same
-
, (2008/06/13)
Propoxybenzene derivatives represented by the following formula STR1 wherein Ra represents a nitro group, an amino group which may have a protecting group or an --NHCH=C(COO--C1-6 -Alkyl)2 group, Rb represents a hydrogen atom, a protecting group for the hydroxyl group or a substituted sulfonyl group and Xa and Xb, which may be the same or different, each represents a halogen atom, and processes for preparation thereof are disclosed. These derivatives are useful in preparing antibacterial agents.
An (S)-(+)-Lactic Acid Route to (2S,6R,8S)-2,8-Dimethyl-1,7-dioxaspiroundecane and (2S,6R,8S)-2-Ethyl-8-methyl-1,7-dioxaspiroundecane and Demonstration of their Presence in the Rectal Glandular Secretion of Bactrocera nigrotibialis (Perkin)

The chiral iodide resulting from reduction and iodination of the tetrahydropyran-2-yl ether of ethyl (S)-(+)-lactate has been engaged in a free-radical addition to acrylonitrile.The resulting protected hydroxy nitrile, on reaction with pent-4-enylmagnesium bromide afforded (S)-2-tetrahydropyran-2-yloxyundec-10-en-6-one.Oxymercuration of this hydroxy enone, under reversible conditions, employing aqueous acid-tetrahydrofuran, effected simultaneous deprotection and cyclisation, and in situ biphasic demercuration with sodium borohydride provided essentially stereochemically pure (2S,6R,8S)-2,8-dimethyl-1,7-dioxaspiroundecane .Epoxidation of the protected hydroxy enone, followed by dimethylcuprate ring-opening and cyclisation, provided a mixture of the (E,E) and the two possible (E,Z)-diastereomers of 2-ethyl-8-methyl-1,7-dioxaspiroundecane with the former being the (2S,6R,8S) stereoisomer.Separation of the (E,E) from the two (E,Z) isomers was achieved by preparative gas chromatography.GC analysis of these samples and of the rectal glandular secretion of male Bactrocera nigrobialis, using a cyclodextrin-based phase, demonstrated that (2S,6R,8S)-stereoisomers of the 2,8-dimethyl-and 2-ethyl-8-methyl-1,7-dioxaspiroundecanes were the natural products, with no detectable level of the antipodes.
