1,2:3,4-Di-O-isopropilideno-α-D-galactopiranose

Descrição:

1,2:3,4-Di-O-isopropilideno-α-D-galactopiranose é um derivado de carboidrato, especificamente uma forma protegida de α-D-galactopiranose. Este composto apresenta dois grupos isopropilideno que servem para proteger os grupos hidroxila no açúcar, aumentando sua estabilidade e reatividade em aplicações sintéticas. Normalmente é um sólido cristalino branco a off-white, solúvel em solventes orgânicos como diclorometano e metanol, mas menos solúvel em água devido aos seus grupos isopropilideno hidrofóbicos. A presença desses grupos protetores permite reações seletivas em posições específicas da molécula de açúcar, tornando-o valioso na síntese orgânica e na química de carboidratos. O composto é frequentemente utilizado na síntese de carboidratos mais complexos e glicosídeos, facilitando o estudo de reações de glicosilação. Sua estrutura pode ser analisada usando técnicas como RMN e espectrometria de massas, que fornecem informações sobre sua configuração molecular e pureza. No geral, 1,2:3,4-Di-O-isopropilideno-α-D-galactopiranose é um intermediário importante na química de carboidratos.
