Diphenyl 2-pyridylphosphine and di-tert-butylazodicarboxylate:Convenient reagents for the Mitsunobu reaction
摘要:
New reagents that resolve the problem of separating products from the numerous byproducts in the Mitsunobu reaction have been introduced. Substitution of a basic triarylphosphine and an acid labile azodicarboxylate for triphenylphosphine and diethy azodicarboxylate provide an improved procedure allowing for facile isolation of desired products in good yields and excellent purity.
