Novel molecular rearrangements of 4-hydroxy-2-cyclopentenones

Novel rearrangements of hydroxycyclopentenone derivatives 1 and 24 to 7,9,11 and 31,33,35 are reported. The stereochemistry of the rearrangement is interpreted as the result of synchronous enolate induced [1.5]-sigmatropic rearrangement and stepwise addition-elimination process. Preparation of the various substrates and structural elucidation of new products are also described.
