Abstract:	Enantioselective synthesis of two anti-tumor antibiotics, (−)-methylenolactocin and (−)-protolichesterinic acid, has been achieved through titanocene(III) chloride mediated radical cyclization reaction starting from commercially available d-mannitol. Titanocene(III) chloride (Cp₂TiCl) was prepared in situ from commercially available titanocene dichloride (Cp₂TiCl₂) and zinc dust in THF.

Keywords:	Enantioselective Titanocene(III) chloride Radical Methylenolactocin Protolichesterinic acid
