Stereodivergent Dual Catalytic α-Allylation of Protected α-Amino- and α-Hydroxyacetaldehydes.

Angewandte Chemie (International ed. in English)

Sandmeier T, Krautwald S, Zipfel HF, Carreira EM.
PMID: 26427612
Angew Chem Int Ed Engl. 2015 Nov 23;54(48):14363-7. doi: 10.1002/anie.201506933. Epub 2015 Oct 02.

Fully stereodivergent dual-catalytic α-allylation of protected α-amino- and α-hydroxyacetaldehydes is achieved through iridium- and amine-catalyzed substitution of racemic allylic alcohols with chiral enamines generated in situ. The operationally simple method furnishes useful aldehyde building blocks in good yields, more...
