- diastereomers, it was suggested that the absolute configuration of natural cis-solamin was 71a. In 2002, Brown’s group [43] also reported the synthesis of cis-solamin (71a) and its diastereomer 71b using the diastereoselective permanganate-promoted oxidative cyclization of 1,5-dienes to create the THF diol core
- (Scheme 11). Notably, no protecting groups were required during the stages of fragment assembly. The synthesis of precursor 78 for the oxidative cyclization reaction was completed by hydrolysis of 77 and activation of the resulting unsaturated acid as the acid chloride followed by reaction with lithiated
- (2S)-10,2-camphorsultam. The key oxidative cyclization reaction, conducted under phase-transfer conditions, introduced the C15, C16, C19, and C20 stereocenters present in cis-solamin in one step, then the auxiliary was best removed from 79 by reduction using NaBH4. The resulting diol was taken forward
