چکیده
The title compound, C(26)H(38)O(6)·H(2)O, is a mono-ester of a derivative of maleopimaric acid, an abietic-type acid. The two fused and unbridged cyclo-hexane rings adopt approximate chair conformations while the three other three six-membered rings have boat conformations.

The title compound, C(24)H(40)O(3)·C(2)H(6)O, is a substituted tetra-cyclo-[10.2.2.0(1,10).0(4,9)]hexa-decane derivative obtained from the reduction of maleopimaric acid which was isolated from a maleic anhydride modified rosin. In the crystal, the triol mol-ecule and the ethanol solvent mol-ecule are linked by hydroxyl O-H⋯O hydrogen bonds, giving a two-dimensional network structure.

The title compound, C(26)H(37)NO(5), which was synthesized from monoethano-lamine and maleopimaric acid, consists of two fused and unbridged cyclo-hexane rings. They form a trans ring junction with a chair conformation. The two methyl groups are in axial positions. In the crystal, inter-molecular O-H⋯O hydrogen bonds link adjacent mol-ecules into a layer structure. Two C-H⋯O interactions are al...
متن کاملDetermination of structure and composition of suberin from the roots of carrot, parsnip, rutabaga, turnip, red beet, and sweet potato by combined gas-liquid chromatography and mass spectrometry.
Suberin from the roots of carrots (Daucus carota), parsnip (Pastinaca sativa), rutabaga (Brassica napobrassica), turnip (Brassica rapa), red beet (Beta vulgaris), and sweet potato (Ipomoea batatas) was isolated by a combination of chemical and enzymatic techniques. Finely powdered suberin was depolymerized with 14% BF(3) in methanol, and soluble monomers (20-50% of suberin) were fractionated in...

Chiral oxazoline based bi and hexadentate ligands built on cyclophosphazene cores have been synthesized and characterized. (NPPh2)2[NP(m-OC6H4C(O)OCH3)2] (1) was prepared by the reaction of gem-(NPPh2)2(NPCl2) with methyl-3-hydroxy benzoate in the presence of Cs2CO3. Compound 1 was converted to the dicarboxylic acid (NPPh2)2[NP(m-OC6H4C(O)OH)2] (2) by base promoted hydrolysis with KO(t-Bu). The...
متن کاملPreparation and Characterization of Rosin-based Waterborne Polyurethane from Maleopimaric Acid Polyester Polyol
Maleopimaric acid (MPA) can be used for polymer materials as a rosin derivative. In this study, rosin-based waterborne polyurethane (RWPU) was prepared with different content of maleopimaric acid polyester polyol (MAPP), which was synthesized from MPA. The properties of RWPU were studied by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and differential scann...
