Pd(PPh3)4-catalyzed reaction between aryl or vinyl iodides and ethyl diazoacetate (EDA) leads to the formation of cross-coupling products in good yields. Copyright
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
RHODIUM(II) ACETATE-CATALYZED REACTION OF ETHYL 2-DIAZO-3-OXOPENT-4-ENOATES: SIMPLE ROUTES TO 4-ARYL-2-HYDROXY-1-NAPHTHOATES AND β,γ-UNSATURATED ESTERS. THE DIANION OF ETHYL 4-(DIETHYLPHOSPHONO)ACETOACETATE AS A PROPIONATE EQUIVALENT

Rhodium(II) acetate-catalyzed decomposition of ethyl 2-diazo-3-oxopent-4-enoates results in the formation of either 4-aryl-2-hydroxy-naphthoates or β,γ-unsaturated esters.In the latter transformation, the dianion of 4-(diethylphosphono)acetoacetate functi
