geraniolDegradation of geraniol (3,7-dimethylocta- trans-2,6-dien-1-ol) biosynthesized in Rosa dilecta has proved that C-10 is exclusively derived from C-2 of mevalonate. This verifies the generally accepted but hitherto unproven view of the origin of the gem-methyls in this compound and ...
gem 在有机物质的命名上表示：在同一个碳上。在这里是指两个溴在同一甲基上 同（碳）-二溴甲基芳烃
The straightforward synthesis of four GEM-difluoromethylenated analogues of pironetin is described. Our synthesis features the efficient construction of the key intermediates through the indium-mediated GEM-difluoropropargylation of aldehydes with the fluorine-containing building block.关键词: pironetin alph...
