Passage: Asymmetric allylboration demonstrates another useful application of organoboranes in carbon<unk>carbon bond formation. In this example from Nicolaou's synthesis of the epothilones, asymmetric allylboration (using an allylborane derived from chiral alpha-pinene) is used in conjunction with TBS protection and ozonolysis. Overall, this provides a two-carbon homologation sequence that delivers the required acetogenin sequence. Swali: Ulinzi wa TBS na oznolysis pamoja na nini hutoa mlolongo unaohitajika wa acetogenin?
