Demonstrated high efficiency in the cyclization process with minimal waste.
Achieved significant improvements in the synthesis route compared to traditional methods.
Abstract
A highly step- and atom-economical cascade 4 + 2/3 + 2 cyclization has been developed for the synthesis of structurally novel spiroimidazolines. Catalyzed by only 1 mol% B(C₆F₅)₃ in the...
