Mechanism and stereochemical control in the .alpha.-haloketal cyclization. Remarkable effect of metal cations
摘要:
A one-pot two-step phosphorylation procedure is described which is suitable for the preparation of thermally lacible or highly substituted dialkyl phosphonates for use in Horner-Emmons olefinations. Such systems are not readily available using the traditional methods such as the Arbuzov reaction or acylation of dialkyl phosphonate carbanions. Reaction of dioxinone lithium enolates with diethyl...
