β¦ Synopsis
Reaction of the imine derived from L-tryptophan methyl ester and senecialdehyde with Fmoe-L-Pro-Cl induces an acyliminium Pictet-Spengler condensation, yielding a mixture of cis and trans tetrahydro-13-carbolines. Deprotection of the cis product with concomitant diketopiperazine formation afforded the natural product in 20 % overall yield.
