A ABORDAGEM TELESCÓPICA COMO FERRAMENTA DA QUÍMICA VERDE
Autor: Vitor S. C. de Andrade, Marcio C. S. de Mattos
Publikováno v: Química Nova, Vol 44, Iss 7, Pp 912-918 (2021)
THE TELESCOPIC APPROACH AS A TOOL FOR GREEN CHEMISTRY. One-pot reactions have become a powerful tool for the development of sustainable protocols in organic synthesis. In particular, the telescoping of multi-step reactions, i.e., the execution of seq
