  2-Substituted (E)-2-(2-lithioethenyl)-1,3-dioxolanes: New diastereoisomeric pure β-acylvinyl anion equivalents

  摘要：

  The reaction of (E)-chloroketals 1 with lithium powder and a catalytic amount of DTBB (4 mol %) in THF at -90 degrees C followed by treatment with different electrophiles [H2O, D2O, Bu(t)CHO, PhCHO, Me(2)CO,(CH2)(4)CO, PhCOMe] at -90 to -60 degrees C affords, after hydrolysis with water, the expected functionalised protected (E)-alpha,beta-unsaturated ketones 3. The deprotection of products 3 is easily achieved with silica gel/aqueous oxalic acid (cat.) to yield (E)-functionalised alkenones 5.

  Ketalised α- and β-lithiated α,β-unsaturated ketones: New masked acylvinyl anion equivalents

  摘要：

  The reaction of chloroketals 1, 5 and 10 with an excess of lithium powder and a catalytic amount of DTBB (4-5%) in THF at -78 or -90 degrees C leads to the corresponding functionalised organolithium compounds 2, 6 and 11, respectively, resulting from a chlorine/lithium exchange; treatment of these intermediates with different electrophiles [H2O, D2O, Me(3)SiCl, Bu(t)CHO, PhCHO, Me(2)CO, (CH2)(4)CO, (CH2)(5)CO, PhCOMe] affords, after hydrolysis with water, the corresponding products 3, 7 and 12, respectively. Careful acidic hydrolysis of these ketalised products with a 10% aqueous solution of oxalic acid leads to the expected ketones 4, 9 and 13, respectively. (C) 1997 Elsevier Science Ltd.
