Engineering Reactions in Crystalline Solids: Radical Pairs in Crystals of Dialkyl 1,3-Acetonedicarboxylates.

Organic letters

Yang Z, Garcia-Garibay MA.
PMID: 10891202
Org Lett. 2000 Jun 29;2(13):1963-1965. doi: 10.1021/ol006042+.

Crystalline dialkyl 1,3-acetonedicarboxylates give dialkyl succinates in high chemical yields by combination of alpha-carbonyl radical pairs produced by photochemical decarbonylation. It is proposed that the solid-state reaction depends on the exothermicity of two consecutive bond cleavage processes. It is...

In anoxic environments, microbial activation of alkanes for subsequent metabolism occurs most commonly through the addition of fumarate to a subterminal carbon, producing an alkylsuccinate. Alkylsuccinate synthases are complex, multi-subunit enzymes that utilize a catalytic glycyl radical and require...
