The first enantiocontrolled synthesis of (3S,8S)-(-)-4,6-decadiyne-1,3,8-triol isolated from a toxic mushroom gymnopilus spectabilis
摘要:
The first synthesis of (3S,8S)-(-)-4,6-decadiyne-1,3,8-triol, isolated from a toxic mushroom Gymnopilus spectabilis, has been achieved by employing the chiral 3-hydroxyalkyne formation reaction as the key step.

Three syntheses of (2S, 3R)-2,5-dihydroxy-3-methylpentanoic acid (verrucarinic acid) and its derivatives suitably protected for the further transformation to macrocyclic trichothecenes are described. These involve an enantioselective ester hydrolysis by pig liver esterase, a Sharpless epoxidation and an asymmetric hydroboration.

This paper describes two enantioselective aziridine-based routes toward 1β-methylthienamycin, 2, and related carbapenems, the key steps being completely regioselective ring-opening reactions of the chiral aziridines 7 and 10 with AlMe3.
