  Lewis Acid-Promoted Deoxygenative Di[β,β-bis(ethylthio)]vinylation of Aldehydes with Trimethylsilylketene Bis(ethylthio)acetal

  摘要：

  Silylketene dithioacetal 1 reacted with aldehydes 2a-o, 14, or cinnamaldehyde (11) in the presence of Lewis acid to give deoxygenative divinylation products, 3-substituted 1,4-pentadienes 3a-o, 15, or 5-phenyl-1,3,6-heptatriene 13b, in good to moderate yields. Similar reaction with 2-aminobenzaldehyde (16) or salicylaldehyde (17) produced quinoline 19 or chroman 20 in 40-58% yield. Treatment of 1 with a-diketones 22a-c or a-ketoester 24 led to tetrasubstituted furans 23a-c or allylic alcohol 25, respectively, in rather low yields. The formation mechanisms of these products are discussed.

  Pestalotiopsis microspora (top right), an endophytic fungus commonly found in tropical plants, was cultured from the lesions in a pandanus leaf (top left). The bioactive ambuic acid (lower right), produced by P. microspora, provides an ideal illustration for the recently developed solid-state NMR FIREMAT technique (see representative spectra lower left), from which the stereochemistry and other structural features may be obtained when single-crystal X-ray results are unavailable.
