Two new glycosides from Dianella ensifolia (L.) DC
Fan, Miao-Yin,Liu, Bing-Rui,Yang, Fan,Zhang, Pu-Zhao
, p. 18 - 20 (2021/11/11)
The Dianella genus includes approximately 20 species in all over the world. So far, only the chemical constituents of the lipophilic extract from Dianella ensifolia have been investigated. However, there have been no reports of its aqueous extract. In thi
WAVELENGTH DEPENDENT PHOTOISOMERIZATION OF BICYCLOHEXENONES
Dauben, William G.,Cogen, Jeffrey M.,Behar, Victor,Schultz, Arthur G.,Geiss, William,Taveras, Arthur G.
, p. 1713 - 1716 (2007/10/02)
The unusual wavelength dependent product selectivity observed upon irradiation of a substituted 2,5-cyclohexadien-1-one is shown to result from wavelength dependent quantum yields for rearreangement of the primary photoproduct bicyclohexenones.Reaction selectivity can be optimized by careful choice of irradiation wavelength and length of irradiation time.
Improved Synthesis of Dichloroisoeverninic Acid
Dornhagen, Juergen,Scharf, Hans-Dieter
, p. 1541 - 1549 (2007/10/02)
The Dichlorination of methyl isoeverninate 7a gave the geminal dichloroketone 12 as the major product.The title compound 1 was therefore synthesized via dichlorination of 4-protected methyl orsellinate 5a using the pivaloyloxy-function as a new protecting group in resorcyclic acids chemistry. - Keywords: 3,5-Dichloro-4-hydroxy-2-methoxy-6-methylbenzoic Acid, Dichloroisoeverninic Acid
2,3-Alkadiensaeureester als Dienophile; Anwendung bei der Synthese von (+)-(R)-Lasiodiplodin
Fink, Margot,Gaier, Hans,Gerlach, Hans

Methyl 2,3-alkadienoates 2 are shown to react at 80 deg C with 1,1-dimethoxy-3-trimethylsilyloxy-1,3-butadiene (1) to give the adducts 3 in good yields.Rearrangement of 3, catalyzed by p-toluenesulfonic acid or by sodium methoxide, affords the 6-substitut
2'-O-Methyltenuiorin, 2"-O-Methyltenuiorin and 2',2"-Di-O-methyltenuiorin. Three News Tridepsides from the Lichen Pseudocyphellaria faveolata
Elix, John A.,Lajide, Labunmi
, p. 2005 - 2011 (2007/10/02)
The tridepsides 2'-O-methyltenuiorin, 2"-O-methyltenuiorin and 2',2"-di-O-methyltenuiorin have been isolated from the lichen Pseudocyphellaria faveolata in addition to the well known compounds tenuiorin, physciosporin and sticnic acid.The structure of the
