Procedure

In the reaction of the third stage, sodium ethoxide is allowed to act on (C) 1,5-bis(4-tert-butylphenyl)-penta-1,4-diyn-3-one, and then sodium sulfide prepared from sulfur and sodium borohydride is allowed to act on (C) so as to cause a cycloaddition reaction, there by obtaining (D) 2,6-bis(4-tert-butylphenyl)-4H-thiopyran-4-one.

Workup

  1. customa cycloaddition reaction, there
