Synthesis of 2-spirocyclopropylglucose via condensation of erythrose with the lithium enolate of 2,6-di-tert=butyl-4-methylphenyl cyclopropanecarboxylate
摘要:
Glyceraldehyde, erythrose, and threose are condensed with the enolate derived from cyclopropanecarboxylic acid BHT ester. The conversion of two diastereomeric products of this condensation into new 2-spirocyclopropyl-substituted aldopyranoses is described.
