Grupos Protectores
Los grupos protectores se utilizan en síntesis orgánica para enmascarar temporalmente grupos funcionales reactivos, permitiendo que ocurran reacciones selectivas sin interferencias. Estos grupos son esenciales para los procesos de síntesis en varias etapas, asegurando que partes específicas de la molécula permanezcan no reactivas mientras se realizan otras reacciones. En esta sección, encontrará una variedad de grupos protectores adecuados para diferentes grupos funcionales, junto con reactivos para su introducción y eliminación. En CymitQuimica, ofrecemos una gama completa de grupos protectores de alta calidad para facilitar sus estrategias sintéticas.
