Ten α,α,α′-trisubstituted cyclododecanones were synthesized and characterized by elemental analyses, infrared, 1^H NMR and 13^C NMR spectra, and X-ray diffraction. NMR data could not give conformational informatio...
Presented in part at the Third National Symposium of the Chinese Chemical Society on Organic Chemistry, Lanzhou, China, August, 2004 (for abstract, see Chin. J. Org. Chem., 2004, Suppl. 365);This project was supported by the National Natural Science Foundation of China (No. 20072053)
cis-1,2-Disubstituted cyclododecanes 2 were synthesized by sodium borohydride reduction of 2-monosubstituted cyclododecanones and their structures were confirmed by 1HNMR, ^13C NMR and elemental analysis. The higher c...
A mangrove endophytic fungus(No.1947)was isolated from the leaves of Kandelia candel from all estuarine mangrove from the South China Sea.The secondary metabolites of this strain were studied firstly in this paper and...
