Ptilomycalin D, a polycyclic guanidine alkaloid from the marine sponge Monanchora dianchora.
A new polycyclic guanidine alkaloid, ptilomycalin D, and the known crambescidic acid were isolated from the marine sponge Monanchora dianchora collected in Nosy-Be, northwest of Madagascar, in theExpand
High glass transition temperature bio-based copolyesters from poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and isosorbide
Abstract New renewable copolymers were prepared from reactive bis-hydroxylated poly(3-hydroxybutyrate-co-3-hydroxyvalerate) oligomers (PHBHV-diol), isosorbide and 1,4-phenylene diisocyanate. First,Expand
Salaramides A and B; Two α-Oxoamides Isolated from the Marine Sponge Hippospongia sp. (Porifera, Dictyoceratida)
TLDR
Two novel α-oxoamides were isolated from the Madagascar marine sponge, Hippospongia sp. Expand
Preparative access to transformation products (TPs) of furosemide: a versatile application of anodic oxidation
Abstract Furosemide, a pharmaceutical prescribed for the treatment of edema and hypertension, is a known contaminant of water. In this study, chemoselective anodic oxidation was implemented to assistExpand
Valorization of glycerol 1,2-carbonate as a precursor for the development of new synthons in organic chemistry
Conjugate addition reactions are efficiently performed by a very simple electrochemical method using nickel complexes as catalysts. In this paper, we reported a new method for the valorization ofExpand
Flexusines A and B and epimukulol from the soft coral Sarcophyton flexuosum.
TLDR
Three new cembranes were isolated from the soft coral Sarcophyton flexuosum collected near Reunion Island, Indian Ocean and their structures were elucidated using 1D and 2D NMR spectral analyses. Expand
7-Amino-7,8-dihydro-α-bisabolene derivatives from the marine sponge Axinyssa aplysinoides
TLDR
Three new compounds isolated from the sponge Axinyssa aplysinoides and structures were discussed on the basis of 1D NMR spectra and their chemotaxonomic significance was discussed. Expand
Valorization of Glycerol 1,2‐Carbonate as a Precursor for the Development of New Synthons in Organic Chemistry.
Activated glycerol carbonate derivatives (halogen or pseudohalide derivatives) such as (I) and (IV) are prepared and subjected to reactions with olefins (II).
Marine Bifunctional Sphingolipids from the Sponge Oceanapia ramsayi
TLDR
Two known sphingolipids have been isolated for the first time from a specimen of the marine sponge Oceanapia ramsayi collected at Itampolo on the west coast of Madagascar in the Indian Ocean. Expand
