Stereoselective synthesis of (7aS)-1-methylenehexahydro-1H-pyrrolizine and (-)-heliotridane from N-diphenylmethyl-(S)-proline ethyl ester

Alkaloid (7aS)-1-methylenehexahydro-1H-pyrrolizine was synthesized from N-diphenylmethyl-(S)-proline ethyl ester by cyclopropanation of the ester group with ethylmagnesium bromide in the presence of titanium tetraisopropoxide, replacement of the protectin
