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

Descripción:

1,2:3,4-Di-O-isopropilideno-α-D-galactopiranosa es un derivado de carbohidratos, específicamente una forma protegida de α-D-galactopiranosa. Este compuesto presenta dos grupos isopropilideno que sirven para proteger los grupos hidroxilo en el azúcar, mejorando su estabilidad y reactividad en aplicaciones sintéticas. Típicamente es un sólido cristalino blanco a blanco sucio, soluble en disolventes orgánicos como el diclorometano y el metanol, pero menos soluble en agua debido a sus grupos isopropilideno hidrofóbicos. La presencia de estos grupos protectores permite reacciones selectivas en posiciones específicas de la molécula de azúcar, lo que lo hace valioso en la síntesis orgánica y la química de carbohidratos. El compuesto se utiliza a menudo en la síntesis de carbohidratos más complejos y glicosidos, facilitando el estudio de reacciones de glicosilación. Su estructura puede ser analizada utilizando técnicas como NMR y espectrometría de masas, que proporcionan información sobre su configuración molecular y pureza. En general, 1,2:3,4-Di-O-isopropilideno-α-D-galactopiranosa es un intermediario importante en la química de carbohidratos.
