Sw. Riesinger et al., A general approach to indolizidine alkaloids from 1-benzyloxy-5-(p-toluenesulfonamido)-3-alken-2-ols: Synthesis of (+)-monomorine I, EUR J ORG C, (12), 1999, pp. 3277-3280
A versatile method for the preparation of indolizidine alkaloids from 1-ben
zyloxy-5-(p-toluenesulfonamido)-3-alken-2-ols as stereodefined key intermed
iates has been developed. The utility of this approach was demonstrated by
the synthesis of (+)-monomorine I.
