Additive Pummerer rearrangements. Asymmetric synthesis of (–)-methyl jasmonate

J. Chem. Soc., Chem. Commun., 1985
Examples of mild, additive Pummerer rearrangements are given; one example involves asymmetric carbon–carbon bond formation as the key step for synthesis of (–)-methyl jasmonate.

Pummerer rearrangements using chlorotrimethylsilane

Journal of the Chemical Society, Perkin Transactions 1, 1984
Attempted Pummerer rearrangement of 3-methoxycarbonylthian-4-one S-oxide in refluxing acetic anhydride gives unexpected products in which β-carbon oxidation and ring contraction has taken place. Treatment of 3-methoxycarbonylthian-4-one with N-chlorosuccinimide gives similar rearrangement products.

PUMMERER REARRANGEMENT OF ETHYL METHYLSULFINYLTHIOACETATE

Phosphorus, Sulfur, and Silicon and the Related Elements, 1990
Abstract Ethyl methylsulfinylthioacetate undergoes Pummerer rearrangement with thionyl chloride, trifluoroacetic anhydride or with acetic anhydride-trifluoroacetic anhydride mixture, but not with acetic anhydride alone. These reactivities are compared to those for methyl methylsulfinylacetate and ω-methylsulfinylacetophenone and interpreted in terms of

Fluoro-Pummerer rearrangement and analogous reactions

Journal of Fluorine Chemistry, 2012
Abstract Fluorine containing compounds hold huge promise for pharmaceuticals and agrochemicals due to their specific therapeutic potency or pesticide properties. Therefore, the development of selective and efficient methods for the introduction of fluorine or fluorinated groups into organic molecules is one of the most important tasks in ...
