摘要：

We describe a ten stage synthesis of an advanced intermediate for elaboration into ergot alkaloids, from 4-carbomethoxyindole. The key step involved an intramolecular cyclisation involving the allyl cation derived from N-benzenesulphonyl, 3-(3'-methoxyprop-2'-en-1'-yl), 4-(1'-hydroxy-2'trimethylsilylmethyl-prop-2'-en-1'-yl)-indole.
