A novel stereoselective synthesis of (E)-2-arylvinylphosphonates in InCl3–NaBH4–MeCN system
摘要:
Hydroindation of arylalkynylphosphonates gives a intermediate which can be hydrolyzed to (E)-2-arylvinylphosphonates in InCl3-NaBH4 MeCN system, the stereoselectivity and yield are rather high, but under the same conditions 2-alkylalkynylphosphonates do not react very well.
