S. Chandrasekhar et Cd. Roy, A BETA,BETA,BETA-TRIALKOXYETHYLLITHIUM STABLE TOWARDS FRAGMENTATION -A CARBOXYL PROTECTED ACETIC-ACID DIANION EQUIVALENT, Tetrahedron, 50(27), 1994, pp. 8099-8102
The novel alkyllithium 1b is not only intriguingly stable towards frag
mentation, but also a synthetically useful reagent, complementing curr
ent carboxylic ester enolate methodology. Its design is based on inter
esting mechanistic principles, and harnesses the known stability of th
e 2,4,10-trioxaadamantane framework.
