propargyl-allenyl Claisen rearrangement and isomerization of the resultant 3,4-dienone to give 2,4-unsaturated fluoroalkyl ketones 4a-c (Z/E mixture). The reaction of ethyl α-per(poly)fluoroalkyl acetate 1 with 1-phenyl propargyl alcohol 5 in refluxing CH2Cl2 in the presence of the mixed base (Na2CO3/TEA) directly afforded the corresponding unsaturated fluoroalkyl ketone 6a-c in one pot. In the presence

Provided herein are hydroxypyridone derivatives, for example, a compound of Formula I, and pharmaceutical compositions thereof. Also provided herein are methods of their use for treating, preventing, or ameliorating one or more symptoms of a proliferative disease.
A process for preparing a halogenated aliphatic-α,β-unsaturated-β-nucleophile-functionalized carboxylate ester having the formula: R1-C(-Nu)=CH-COOR8 by reacting a nucleophile with a halogenated aliphatic-α,β-unsaturated-β halocarboxylate ester having the formula: R1-CX1=CH-COOR8, wherein R1 is selected from the group consisting of straight chain and branched halogenated C¿1?-C12 aliphatic groups; Nu is a nucleophile moiety different from X?1; X1¿ is F, Cl or Br; and R8 is selected from the group consisting of straight chain and branched C¿1?-C6 alkyl groups. Halogenated aliphatic-α,β-unsaturated-β-nucleophile-functionalized carboxylate esters, halogenated aliphatic-α,β-unsaturated-β-halocarboxylate esters, and intermediate compounds and processes in the preparation thereof are also disclosed.
