The synthesis of the phytoprostane B1 types I and II is achieved in high overall yield (35−53%) by only two principal transformations starting from 1,3-cyclopentanedione. The first side chain is attached via O-acylation of the 1,3-dione followed by rearrangement and reduction to give the 2-alkyl-1,3-diones 4a−c. After conversion into the corresponding vinylic iodides 5a−c, the second side chain is
