  摘要：

  Lithiated 2-buten-4-olide was found to react with aromatic aldehydes regioselectively at gamma-position to provide 4-(1-aryl-1-hydroxymethyl)-2-buten-4-olides which could be readily converted into the corresponding (Z)-gamma-arylidenebutenolides.

  a set of hydroxyphenyl γ-valerolactones was achieved starting from 2-silyloxyfuran and alkoxy-substituted benzaldehydes as common precursors. Key synthesis steps included an enantioselective vinylogous Mukaiyama aldol reaction and a Barton–McCombie deoxygenation. Five enantioenriched γ-valerolactone targets were obtained in 5–6 steps, 18–63% overall yields and 82–98 % ee, paving the way for the straightforward

  从2-甲硅烷氧基呋喃和烷氧基取代的苯甲醛作为常见的前体开始，实现了一组羟苯基γ-戊内酯的不对称合成。关键的合成步骤包括对映选择性的乙烯基Mukaiyama aldol反应和Barton-McCombie脱氧反应。通过5–6个步骤获得了5个对映体富集的γ-戊内酯目标，总产率为18–63％，ee为82–98％，这为直接进入此类具有生物有效性且难得的flavan -3-ol代谢物铺平了道路。同时，偶然发现了一种空前的一锅还原环扩展过程，从酚丁醇化物前体产生外消旋的δ-内酯类似物。

  The formation of chiral γ‐butenolides has been achieved with good yields (up to 90%), high enantioselectivity (up to 91%) and diastereoselectivity (up to 9/1, anti‐selective) through an organocatalyzed vinylogous Mukaiyama aldol reaction of 2‐(trimethylsilyloxy)furan and aldehydes. A wide range of chiral γ‐butenolides was obtained under mild conditions by this methodology.

• The first organocatalytic addition of 2-trimethylsilyloxyfuran to carbonyl compounds: hydrogen-bond catalysis in γ-butenolides synthesis

  日期：2006.11

  This letter describes the first example of diastereoselective 'organocatalyzed' synthesis of the butenolide products substituted at the gamma-position by a chain bearing hydroxyl groups. The urea-derivative 4 has proved to be an efficient catalyst for the addition of the commercial TMSOF to carbonyl compounds under solvent-free conditions. The reaction conditions and generality of the procedure have been examined. (c) 2006 Elsevier Ltd. All rights reserved.
