Tributyltin hydride-mediated radical cyclization of the (2S)-N-(α-chloroacetyl)-2-ethenylpyrrolidines 13a, b and 15 and the bis(phenylthio)acetyl congener-14 derived from (S)-prolinol gave (1R, 7aS)-hexahyrdo1-methyl-3H-pyrrolizin-3-one (17) and its derivatives 16a, b in highly regio- and diastereo-selective manner. This radical cyclization was successfully applied to the formal total synthesis of (-)-trachelanthamidine.
