Qodobka: Asymmetric allylboration wuxuu muujinayaa codsi kale oo faa'iido leh oo organoboranes ah oo ku saabsan sameynta carbon<unk>carbon bond formation. Tusaalahan ka soo baxa Nicolaou ee epothilones, asymmetric allylboration (iyadoo la adeegsanayo allylborane oo laga soo qaatay chiral alpha-pinene) waxaa loo isticmaalaa iyada oo lala kaashanayo ilaalinta TBS iyo ozonolysis. Guud ahaan, tani waxay bixisaa taxane laba-carbon ah oo soo saara taxanaha loo baahan yahay ee acetogenin. Su'aal: TBS ilaalinta iyo oznolysis oo ay weheliso waxa keenaya taxanaha loo baahan yahay ee acetogenin?
