, p. 2951 - 2952 (1984)
Two new diunsaturated lipids, related to palmitic acid, were isolated from the brown alga Cystoseira barbata, one of which is toxic to mice during P388 lymphocytic leukemia tests. Key Word Index - Cystoseira barbata; Phaeophyceae; brown alga, ethyl-(Z),(Z)-hexadec-10,13-dienate; (Z),(Z)-hexadec-10,13-dienal.
Silica-Mediated Monohydrolysis of Dicarboxylic Esters
Dyker, Gerald
supporting information, p. 6773 - 6776 (2021/12/31)
A new method for the monohydrolysis of dicarboxylic esters is presented, involving as key step a silanolysis at elevated temperatures at the silica gel surface. In the second step, the surface bound silyl esters are cleaved off under mild conditions, giving a straightforward and fast access to half esters. Based on recovered starting material generally yields well above 70 % are achieved, both, with stiff aromatic as well as flexible aliphatic substrates, as long as the ester groups involved are remote enough from each other. Otherwise competing reactions are becoming determinative, anhydride formation in the case of phthalates and decarbonylative fragmentation in the case of malonates. The new method was also successfully tested on a multigram scale with a minimalistic apparatus setup.
