A stereoselective and scalable synthesis of a conformationally constrained S1P1 agonist
摘要:
A scalable and enantioselective synthesis of a potent SIP1 agonist containing two stereogenic centers oil a cyclopentane ring is described. Control of the absolute chirality of an amino alcohol precursor, generated via a robust phase-transfer catalyzed alkylation protocol, allows for Substrate directed hydrogenation to install the second stereogenic center providing access to gram-quantities of compound 2.
