  trans-Penta-2, 4-dienyl phenyl ether (trans-1), on heating at 186° in a five-fold excess of N, N-diethylaniline, gave via a [3s, 3s] rearrangement 23% of 2-(1-vinyl-allyl)-phenol (2) and via a [5s, 5s] rearrangement 37% of trans-4-(penta-2, 4-dienyl)-phenol (trans-3). The dimeric residue was formed from trans-1 by diene synthesis. By working at high dilution, the formation of dimeric products was kept

• Synthesis of Alkylidenecyclopentenones and Dialkylidenecyclopentenones via the Coupling of Propargylic Alcohol and 2-Alkyne-1,4-diol Derivatives with Cyclopropylcarbene–Chromium Complexes

  日期：2000.7

  The coupling of propargylic alcohols and their derivatives with cyclopropylcarbene-chromium complexes has been investigated. The coupling reaction leads to alkylidenecyclopentenones or alkoxyalkyl-cyclopentenones, depending on the leaving group ability of the propargyl substituent. A mechanism involving formation of a cyclopentadienone, followed by reduction and beta-elimination is proposed. Coupling of cyclopropylcarbene complexes with 2-alkyne-1,4-diol derivatives leads to dialkylidenecyclopentenone derivatives via a double elimination process. (C) 2000 Elsevier Science Ltd.

• Au-Catalyzed Synthesis of (1<i>Z</i>,3<i>E</i>)-2-Pivaloxy-1,3-Dienes from Propargylic Pivalates

  日期：2008.3.1

  Propargylic pivalates with electronically unbiased internal alkynes are selectively transformed into (1Z,3E)-2-pivaloxy-1,3-dienes containing various functionalities. The unusual selectivity of 1,2-acyloxy migration over the structurally preferred 3,3-rearrangement is realized. This reaction is highly stereoselective and offers rapid access to dienes for one-pot intra-/intermolecular Diels-Alder reactions either under thermal conditions or with Lewis acid catalysis.
