Ground and excited state 1,4-addition reactions of some carbohydrate enones
Abstract
Highly functionalised branched-chain monosaccharides can be prepared by sensitised irradiation of conjugated enones (1) and (2) in an alcohol whereupon equatorial 1,4-addition of the carbinol is the major event, the adducts so obtained being correlated with the products of ground-state additions.
