标题:用光不稳定的羰基保护基氧化
摘要:已经开发出一种新的氧化方法,该方法利用了坚固的光不稳定的羰基保护基试剂(1)作为氧化剂.与现有方法不同,该方法将伯醇氧化为光敏乙缩醛(例如3),为受保护的醛提供了另一种独特的方法.因此,第一次在一个反应中实现了氧化和保护.仲醇被氧化成相应的酮.此外,光不稳定的保护基团(ppg)还会氧化醚和酯.氧化大概是通过在酸性条件下从1生成的三苯甲基离子通过氢化物提取来实现的.但是,伯醇和仲醇的机理略有不同.

标题 :Enzymatic synthesis of kavalactones and flavokavains
发明人：PLUSKAL TOMÃ?S; Weng jing-ke
权利人:WHITEHEAD INST BIOMEDICAL RES
摘要:Disclosed are methods, compositions, proteins, nucleic acids, cells, vectors, compounds, reagents, and systems for the preparation of kavalactones, flavokavains, and kavalactone and flavokavain biosynthetic intermediates using enzymes expressed in heterologous host cells, such as microorganisms or plants, or using in vitro enzymatic reactions. This invention also provides for the expression of the enzymes by recombinant cell lines and vectors. Furthermore, the enzymes can be components of constructs such as fusion proteins. The kavalactones produced can be utilized to treat anxiety disorder, insomnia, and other psychological and neurological disorders. The flavokavains produced can be utilized to treat various cancers including colon, bladder, and breast cancers.
