RUTHENIUM-CATALYZED CROSS METATHESIS OF VINYL PHOSPHONATE WITH VINYL ACETALS: AN EFFICIENT ROUTE TO(3-OXO-PROPENYL)-PHOSPHONATES
【摘要】:正For our work on developing novel phosphorus-containing farm chemicals we needed (3-oxo-propenyl) -phosphonates as key intermediates. A few synthetic methods have been reported for this class of compounds, for example, an Arbuzov reaction of 2-bromomethyl oxirane and P(OR)3, followed by ring opening and oxidation. Instead of this elegant methodology, we would like to develop a shorter procedure to make such compounds. In addition
