资源简介：
A highly
enantioselective [4+2] annulation with respect to allenoates and 3-olefinic
oxindoles catalyzed
by Lewis base was reported, which proved to be an efficient way to
synthesize chiral dihydropyran-fused indoles. The cycloaddition products
were generally obtained in high yields (up to 98%) with very good
enantioselectivities (up to 94% enantiomeric excess).
