Syntheses of C2-symmetric vicinal diamines derived from tartaric acid
摘要:
C-2-symmetric vicinal diamines 3b-f, derived from L-tartaric acid, with increasingly bulky terminal ether functionalities were prepared using two distinct sequences. Diamines 3b,c were obtained from the corresponding vicinal diols 4b,c, while diamines 3d-f were generated from dihydroxydiazide 7 via deprotection-reprotection strategies.
