ChemInform Abstract: Divergent Synthesis of α,γ‐Disubstituted γ‐Butyrolactones Through Diastereoselective Bromolactonization with Alkali Metal Bromide: Asymmetric Total Synthesis of (+)‐Dubiusamine C

The diastereoselective bromolactonization of α‐substituted 4‐pentenoic acids and 4‐pentenamides by oxidative umpolung of bromide ion using alkali metal bromide with Oxone is investigated.
