A new chiral titanium species for the ring opening reactions of meso epoxides
摘要:
The synthesis of a new chiral ligand 1 based on the conformationally defined 1,7-dioxaspiro[5.5]undecane ring system is reported. Generation of the corresponding ligand 1-Ti(OiPr)(4) complex as a catalyst and its use in the enantioselective ring opening reaction of cyclohexene oxide with TMSN3 is described.
