Practical stereoselective synthesis of α-d-C-mannosyl-(R)-alanine
摘要:
a-D-C-Mannosyl-(R)-alanine 2 was synthesized in only four steps starting from the known acetonide protected D-ribo-hex-1-enitol 4 and N-benzoylalanine. The key C-C bond formation between the sugar and the amino acid moieties was effected through a Claisen rearrangement of the intermediate oxazole 7, derived from the ester 6.
