  Tandem reduction–olefination of triethyl 2-acyl-2-fluoro-2-phosphonoacetates and a synthetic approach to Cbz-Gly-Ψ[(Z)-CFC]-Gly dipeptide isostere

  摘要：

  (Z)-alpha-Fluoro-alpha,beta-unsaturated esters (Z)-7a-f were stereoselectively prepared by a tandem reduction-olefination of triethyl 2-acyl-2-fluoro-2-phosphonoacetates 6a-f with NaBH4 in EtOH. A concise synthesis of Cbz-Gly-Psi[(Z)-CF=C]-Gly (26) as a dipeptide isostere was achieved via the tandem reduction-olefination of the corresponding 2-acyl-2-fluoro-2-phosphonoacetate 20.

• Titanium mediated olefination of aldehydes with α-haloacetates: an exceptionally stereoselective and general approach to (Z)-α-haloacrylates
  作者：John Kallikat Augustine、Agnes Bombrun、Srinivasa Venkatachaliah、Anandh Jothi

  DOI：10.1039/c3ob41592a

  日期：——

  An exceptionally stereoselective and general synthesis of (Z)-α-haloacrylates, ready to undergo various synthetic transformations, has been demonstrated from α-haloacetates and aldehydes in a one-pot manner via the titanium-enolate based asymmetric aldol condensation. Besides being an expedient synthetic procedure, the ready availability of diverse α-haloacetates, exceptional stereoselectivity, and high yields make the process a versatile transformation in organic synthesis. The potential of this method in up-scaling operations has been illustrated.

  展示了一种异常立体选择性和通用性合成（Z）-α-卤代丙烯酸酯的方法，该方法通过钛烯醇基催化的不对称 aldol 凝缩反应，采用 α-卤代乙酸酯和醛以一步法进行合成。这种合成方法不仅便捷，而且多样的 α-卤代乙酸酯的可得性、出色的立体选择性和高产率使得该过程在有机合成中具有多功能性。该方法在放大操作中的潜力也得到了展示。
