Abstract
The transformation of sugar enolic ethers into branched sugars through C–H activation
or cross-coupling reaction represents a compelling strategy in carbohydrate chemistry.
These branched sugars serve as versatile intermediates for the synthesis of annulated
sugars, which are key components in numerous biologically active molecules. This Account
highlights various methodologies for the development of branched sugars, focusing
on approaches utilizing glycals and alkenes through C–H activation and cross-coupling
reactions. Additionally, it explores literature reports on the synthesis of chiral
fused ring systems derived from functionalized glycals, offering insights into their
significance in synthetic chemistry.
