6-tert-butyl-4-hydroxy-2H-pyran-2-one Usage And Synthesis

Uses

6-tert-butyl-4-hydroxy-2H-pyran-2-one is an optoelectronic material intermediate capable of synthesizing OLED materials.

Preparation

6-tert-butyl-4-hydroxy-2H-pyran-2-one were prepared under mild reaction conditions by the reaction of 2,2,6-trimethyl-1,3- dioxin-4-one with 1-acylbenzotriazoles 9 in the presence of LDA followed by thermal cyclization.
