“…Oxazolines 232 and 233 were prepared from (-)-norephedrine and (+)-endo-2-hydroxy-endo-3aminobornane (231) and 2fluorobenzoic acid (230) for Tsuji-Trost reactions under the conditions depicted in Scheme 40 [97,98]. Treatment of 232 and 233 with potassium diphenylphosphide gave 234 and 235, respectively.…”

“…Indeed, drugs based on 1,2,3,4-diaminobutanediols and derivatives showed anticancer properties, and complexes of threo-2,3-diaminobutane-1,4-diol derived from mannitol were used as antitumor agents. 7 These compounds are also the precursors of bioxazoles 3 8 and bioxazolidinones 4, 9 useful for asymmetric hydrosilylation and allylic substitution. 10 Our continuing interest in utilizing tartaric acid as a chiral source for the synthesis of optically active products 11 led us to investigate an efficient construction of polyfunctionalized, N-substituted compounds 5 and of the corresponding N,O-formacetals 6 ( Figure 2).…”
