Lipase mediated hydrolysis of rapamycin 42-hemisuccinate benzyl and methyl esters

Adamczyk, Maciej,Gebler, John C.,Mattingly, Phillip G.

, p. 1019 - 1022 (1994)

Benzyl and methyl esters of rapamycin 42-hemisuccinate were hydrolyzed under very mild conditions to the rapamycin hemisuccinate using lipase from Pseudomonas sp. This selective deprotection was performed on a ≥100 mg scale for both esters resulting in 50% isolated yield from the methyl ester and 29% from the benzyl ester of the desired acid.
