β¦ Synopsis
The total synthesis of the marine alkaloid variolin B has been achieved in eight steps, starting from commercially available 4-chloro-2-methylthiopyrimidine. The key reaction involves the tandem deoxygenation and cyclization of a triarylmethanol using a combination of triethylsilane and trifluoroacetic acid.
