摘要
If life deals you a lemon ...: Low selectivity in the [Co(salen)]-catalyzed kinetic resolution of terminal epoxides with N-Boc sulfonamides is parlayed into an efficient one-pot synthesis of enantiopure amino alcohol derivatives. This provides the foundation for a general route to the title compounds (see scheme; Boc = tertbutoxycarbonyl; Ns = 2-nitrobenzenesulfonyl).
