Descrição geral

Methyllithium is an organolithium reagent mainly used for deprotonation and as a source of methyl anion. It is a strong base and a strong nucleophile.

Aplicação

Methyllithium solution (1.6M in diethyl ether) has been used for the asymmetric allylic alkylation (AAA) of allylic electrophiles in the presence of a chiral copper catalyst. This protocol leads to the C-C bond formation of tertiary and quaternary stereogenic centers with high enantioselectivity. It can also be used for the synthesis of (−)-salsolidine by reacting with 6,7-dimethoxy-3,4-dihydroisoquinoline in the presence of (−)-sparteine as a chiral ligand.

Embalagem

The 25 mL Sure/Seal bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
