چکیده
In the title mol-ecule, C(17)H(16)O(4), the angle between the aromatic ring planes is 69.1 (6)°. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds; mol-ecules related by a centre of symmetry are linked to form inversion dimers.

متن کاملA novel synthesis of succinic acid type Gemini surfactant by the functional group interconversion of Corynomicolic acid.
2,3-Bis(undecyl)succinic acid, succinic acid type Gemini surfactant, was successfully synthesized from Corynomicolic acid by the functional interconversion of OH of Corynomicolic acid to COOH via (1) mesylation of OH of syn-isomer, (2) elimination of methanesulfonate group using base to E-alpha,beta-unsaturated ester, (3) Michael addition of CN(-) with 18-crown-6 and (4) hydrolysis. In most hyd...
