A new method for the synthesis of 2-cyclopenten-1-one-5-carboxylic ester derivatives via Rh2(OAc)4-mediated intramolecular C-H insertion reaction of 4Z-β-vinyl-α-diazo β-ketoesters

2-Cyclopenten-1-one-5-carboxylic ester derivatives 14 are synthesized in a four-step-reaction sequence starting from alkynyl aldehydes 9 via 4Z-β-vinyl-α-diazo β-ketoesters intermediate 8. The synthetic method for 8 is described. When the δ substituent is
