P. Mayer et al., SYNTHESIS AND USE OF A NEW SYNTHON - 4-BR OMO-4-DEOXY-L-THREONIC ACIDMETHYL-ESTER, Bulletin de la Societe chimique de France, 130(4), 1993, pp. 509-512
The action of the system PPh3-CBr4 on the 3,4-O-isopropylidene-L-threo
nic acid methyl ester, obtained from L-ascorbic acid, provides a new 4
-bromo threonic derivative with a good yield. This new compound is an
useful intermediate for the synthesis of various natural products as d
ihydromahubanolide or anthopleurine.
