One-pot synthesis of chiral dehydroproline esters: [3+2]-type cycloaddition reaction of allenylstannane and α-imino ester
摘要:
An enantioselective [3+2]-type cycloaddition of allenylstannane and alpha-imino ester was developed. Synthetic utility of the 4stannyldehydroproline ester intermediate was demonstrated: iodine oxidation and Stille coupling reaction of the intermediate afforded optically active 4-iodo- and 4-aryldehydroproline esters in good yields and in high ees, respectively.
