  Diastereoselective addition of lower order vinylcuprates to (R)-2,3-O-Isopropylideneglyceraldehyde

  摘要：

  Highly syn or anti selective addition of lower order lithium vinylcuprates generated from alkenyl bromides 1 to (R)-2,3-O-isopropylideneglyceraldehyde (2) can be achieved, respectively, depending on the substitution pattern of the vinyl moiety and the solvent. Alpha-Trimethylsilyl substituted vinylcuprates possessing an alkyl substituent Z to copper react with excellent syn selectivity in ether whereas a highly anti selective addition is observed for cuprates bearing a hydrogen atom Z or alpha to the metal in THF. A model is proposed to rationalize these complementary selectivities.

  (R)-2,3-O-isopropylideneglyceraldehyde (1) are converted to 3,4,5-trimethoxybenzyl ethers 3 by a one-pot desilylation/alkylation. After deprotonation using potassium t-butoxide/t-butyllithium/N, N N′ N′-tetramethylethylenediamine in t-butyl methyl ether at −78 °C, substrates 3 undergo a [2,3]-sigmatropic Wittig rearrangement with complete 1,3-chirality transfer and good simple diastereoselectivity to give
