Total Synthesis Blog

Hello

First, some nice Total Synthesis of (-)-Aplysiallene published in Organic Letters.

This compound was found in red alga Laurencia okamurai Yamada (in 1985) and in sea hare Aplysia kurodai (in 2001). Retrosynthetc Analysis of (-)-Aplysiallene is presented below. Initially stereochemistry of (-)-Aplysiallene was opposite to stereochemistry presented above. Structure of that target was revised thanks to NMR.

And the way in which real structure of (-)-Aplysiallene was synthesized is shown:
