说明

Application

(−)-Methyl (S)-2,2-dimethyl-1,3-dioxolane-4-carboxylate can be used:

As a chiral building block to make the key tetrahydrofuran subunit of (−)-gymnodimine, a marine algal toxin.
To prepare an enedione by reacting with dimethyl methylphosphonate, BuLi, and phenylglyoxal, which in turn is used to synthesize cyclopentenone derivatives.
As a starting material for the preparation of (S)-4,5-dihydroxy-2,3-pentanedione (DPD), a precursor for autoinducer (AI)-2 in bacteria.

We describe an original, short, and convenient chemical synthesis of enantiopure (S)-4,5-dihydroxy-2,3-pentanedione (DPD), starting from commercial methyl (S)-(-)-2,2-dimethyl-1,3-dioxolane-4-carboxylate. DPD is the precursor of autoinducer (AI)-2, the proposed signal for bacterial interspecies communication. AI-2 is synthesized by many bacterial species in
