Preparations of Z-α,β-Unsaturated Amides by Using Horner-Wadsworth-Emmons Reagents, (Diphenylphosphono)acetamides
31 December 2001 (online)
New Horner-Wadsworth-Emmons reagents, (diphenylphosphono)acetamides 2 react with a variety of aldehydes to give the corresponding Z-α,β-unsaturated amides stereoselectively (up to Z : E = 98 : 2).
amides - alkenes - aldehydes - Horner-Wadsworth-Emmons reaction - Z-selective
