TL;DR: Carbohydrate-derived 2,3:4,6-diacetonides undergo a 6-exo-dig radical cyclization, from a radical located at C-5, to yield highly functionalized cyclohexanes that are correlated with carba-sugars as mentioned in this paper.

TL;DR: Carbohydrate-derived 2,3:4,6-diacetonides undergo a 6-exo-dig radical cyclization, from a radical located at C-5, to yield highly functionalized cyclohexanes that are correlated with carba-sugars as discussed by the authors.
Abstract: Carbohydrate-derived 2,3:4,6-diacetonides which are homologated at C-1 by reaction with phenyl acetylide undergo a 6-exo-dig radical cyclization, from a radical located at C-5, to yield highly functionalized cyclohexanes that are correlated with carba-sugars.
