Synthesis of the taxol core via catalytic asymmetric 1,4-addition of an Alkylzirconium Nucleophile

The Taxol core was prepared in five steps via a key copper-catalyzed asymmetric conjugate addition trapping sequence. The use of a bromodiene-derived alkylzirconium nucleophile followed by trapping with POCl3/DMF gave a highly functionalized intermediate featuring a quaternary center in 69% yield wi...

description The Taxol core was prepared in five steps via a key copper-catalyzed asymmetric conjugate addition trapping sequence. The use of a bromodiene-derived alkylzirconium nucleophile followed by trapping with POCl3/DMF gave a highly functionalized intermediate featuring a quaternary center in 69% yield with 92% ee. After 1,2-addition, Suzuki–Miyaura cross-coupling, allylic oxidation, and a type II intramolecular Diels–Alder reaction, the taxol core was obtained in 11% overall yield with 92% ee.
