How one of Nature's Most Complex Molecules Is Made: Synthesis of Taxol's "Complicated Cousin"

Ғылым және технология

Taxol - a commonly used anticancer drug - is part of a broader family of taxane natural products - which includes Canaxpropellane, Taxol's "complicated cousin". We will explore some of the related - and unrelated :) - history, biochemistry and chemistry facts and trivia.
Even if you are not deeply engaged with total synthesis, I am confident that this video will enrich your understanding of natural sciences.

00:00 Introduction
00:32 Setting the scene for Canataxpropellane
03:48 Propellane nature, reactivity, utility (bicyclopentanes), history (Ginsberg)
07:55 Simple synthesis of [4.4.2] propellane
10:08 Total synthesis of Canataxpropellane by Professor Gaich and co-workers from the University of Konstanz (retrosynthetic analysis, disconnections, forward synthesis, mechanistic disussions, stereoselectivity)

    I think it’s just sterics - even though “the bottom” face looks open, the attack trajectory of nucleophiles would be quite shielded by the bulky acetal group. So the ester gets reduced first. The authors didn’t comment on this - but I wouldn’t be surprised if they saw some reduction, especially at more forcing conditions

    Do you have access to reaxys? This database shows different ways to prepare chemicals Are you talking about direct 5-bromination of tryptophan? Not sure if that is possible, you probably need multiple reactions via the 5 bromoindole or others

    @@totalsynthesis I'm from Ukraine. I am a little difficult to speak English. I do not have access to REAXYS. Give a reference to Reaxys. For me, very interesting foreign works of chemists. Maybe I find something for myself.

    Thanks for that, very clear. However, I expect it will be more complicated on a second viewing!

    This is why I did bad in orgo. Just seeing synthesis after synthesis frustrated me because I need to understand why each step behaves the way it does and they all have some crazy explanation I'm always either skeptical of or don't understand. And then on the tests all my synthesis proposals are wrong. Each step could take hours to days, and your yield is going to be tiny. 26 steps must have taken months.
