资源简介：
A chemodivergent
synthesis of two series of spirochromans depending
on the catalytic system was developed. Starting from diarylideneacetones
and organoboronic acids, asymmetric rhodium catalysis led to the enantioselective
synthesis of 4,4′-disubstituted 2,2′-spirobichromans,
while acid catalysis led to the formation of 4-substituted spirochroman-2,2′-chromenes.
A plausible mechanism of the chemodivergent synthesis was proposed.
