Other methyl nucleophiles includingMeMgBr, MeCeCl2, MeTiCl3, Me3Al, Me3ZnMgCl, MeMnClwere tried, but in all these cases no detectable amount of exo-C8-methylated product was obtained. Although protecting C3-carbonyl as 1,3-dioxolanes could be achieved, the serious enolization of C8-carbonyl was still problematic. Converting C9-furan ring to α,β-butenolide did depress the enolization, but desired C8-methylation was completely replaced by migration of the double bond of the butenolide.

在本論文的早期階段美女操又黄又爽，主要著眼于解決二環(huán)[3.2.1]-C8-羰基加成甲基所遇到的C9-呋喃環(huán)差向異構化和C3與C8兩個羰基之間化學選擇性的問題：通過引入不同金屬降低甲基試劑的堿性并沒有取得甲基化的成功；通過不同的方法將C3-羰基掩蔽av无码aV天天aV天天爽，但是C8-羰基的烯醇化依然無法抑制久久95国产热情精品国产；雖然通過將呋喃環(huán)轉化為α，β-不飽和-γ-丁內酯可以抑制烯醇化人人射人人看性爱视频，但內酯環(huán)上的雙鍵遷移又成了新的競爭反應97免费视频在线观看。

Among all, deleted in liver cell (DLC-1) gene was found to play an important role in hepatoma in 1998, and after that hypermethylation on the promoter of the DLC-1 gene was found in many other cancers, suggesting that epigenetic modification is another way to control the carcinogenesis. Another gene, Endothelin type B receptor, was found to cause megacolon syndrome by accident while searching the cause of white spot in mouse, and was also found hypermethylation on its promoter in some cancer cells.
