- The gene products of AK121211, AK066327, and AK070534 from Oryza sativa encode cycloartenol, parkeol, and achilleol B synthases, respectively. Parkeol synthase is a unique enzyme that affords parkeol as a single product....
- Regioselective Hydroformylation of Allylic Alcohols
[作者:LIGHTBURN THOMAS E; DE PAOLIS OMAR A; CHENG KA H; TAN KIAN L,期刊:Organic Letters, 页码:2686-2689 , 文章类型: Article,,卷期:2011年13-10]
- A highly regioselective hydroformylation of allylic alcohols is reported toward the synthesis of p-hydroxy-acid and aldehyde products. The selectivity is achieved through the use of a ligand that reversibly binds to alco...
- First Total Synthesis of Rhodexin A
[作者:JUNG MICHAEL E; YOO DONGWON,期刊:Organic Letters, 页码:2698-2701 , 文章类型: Article,,卷期:2011年13-10]
- An efficient total synthesis of rhodexin A (1) is reported. An initial inverse-electron-demand Diels-Alder reaction of the acyldiene 6 with the silyl enol ether 7 gave the cycloadduct 8 with the required 4 contiguous ste...
