  4-(Trialkylsilyl)oxybut-2-ynals as dienophiles in the Diels–Alder synthesis of α-(hydroxymethyl)benzaldehydes

  摘要：

  The alpha-(hydroxymethyl)benzaldehyde derivative 2 has been synthesized by heating ynal 3 with diene 5, which produced the alpha-(silyloxymethyl)benzaldehyde 6 by a Diels-Alder retro-Diels-Alder process, followed by methylation, thioacetalization. and removal of the silyl protecting group. Decarbonylation of alpha-(silyloxymethyl)benzaldehydes des 6 and 10 takes place readily in the presence of zinc(II) chloride or para-toluenesulfonic acid. (C) 2001 Elsevier Science Ltd.
