Significance

A general approach to the synthesis of indolizidine alkaloids is reported. A three-component reaction between TBS 1,3-dithiane A, epoxide B and N-toluenesulfonyl aziridine E is used to synthesize the 1,5-amino alcohol derivative F. A subsequent one-pot sequential cyclization protocol was used to form the indolizidine core.
