CHLORO-1 ET CHLORO-3 METHOXYCARBONYLHYDRAZONO-2 PROPYLPHOSPHONATES: REACTIFS D'ALKYLATION D'ENOLATES DE CETONES. ACCES A DES PHOSPHONATES PYRROLIQUES ET A DES β,ε DICETOPHOSPHONATES PRECURSEURS DE CYCLOPENTENONES

The reactivity of keto enolates with 1-chloro and 3-chloro-2-methoxycarbonylhydrazono-propylphosphonates 1 and 2 is studied.It is shown that those enolates react with the chlorohydrazone 1 to give 3-diethoxyphosphonopyrroles 5 under a mechanistic pathway

DIETHYL 3-BROMOPROPENE PHOSPHONATE AN ALKYLATIVE β-KETO PHOSPHONATE EQUIVALENT

A description of the preparation of diethyl 3-bromopropene phosphonate, 1, is reported.The use of this reagent as an acetone equivalent for the annulation of five-membered rings is described.
