A new member of the gymnodimine class of spiroimine toxins has been isolated from a laboratory culture strain of Alexandrium ostenfeldii. Extensive one-dimensional (1D) and two-dimensional (2D) NMR data analysis was used to elucidate its structure as 12-methylgymnodimine B.
متن کاملNovel yellow compounds, dilysyldipyrrolones A and B, formed from xylose and lysine by the Maillard reaction.
When a solution containing xylose and L-lysine is heated under weakly acidic conditions, it turns brown by the Maillard reaction. We isolated here two novel yellow compounds from a heated solution containing xylose and lysine, and identified pyrrolyl-methylidene-pyrrolone derivatives named dilysyldipyrrolones A and B. Their chemical structures were elucidated by instrumental analyses as 6-[[1-[...
متن کاملN′-[(E)-(5-Methylfuran-2-yl)methylidene]formohydrazide
The title compound, C(7)H(8)N(2)O(2), is almost planar (r.m.s. deviation for non-H atoms = 0.029 Å). In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate an R(2) (2)(8) ring motif.
متن کاملSynthesis and asymmetric hydrogenation of (3E)-1-benzyl-3-[(2-oxopyridin-1(2H)-yl)methylidene]piperidine-2,6-dione.
The synthesis of (3E)-1-benzyl-3-[(2-oxopyridin-1(2H)-yl)methylidene]piperidine-2,6-dione 5 from N-benzylglutarimide was achieved in three steps. The asymmetric hydrogenation of 4 gave either the product of partial reduction (10) or full reduction (13), depending on the catalyst which was employed, in high ee in each case. Attempts at asymmetric transfer hydrogenation (ATH) of resulted in forma...
متن کاملRuCl₃·3H₂O catalyzed reactions: facile synthesis of bis(indolyl)methanes under mild conditions.
RuCl₃·3H₂O was found to be an effective catalyst for reactions of indoles, 2-methylthiophene, and 2-methylfuran with aldehydes to afford the corresponding bis(indolyl)methanes, bis(thienyl)methanes, and bis(fur-2-yl)methanes in moderate to excellent yields. Experimental results indicated that mono(indolyl)methanol is not the reaction intermediate under these reaction conditions.
