An expedient synthesis of D-callipeltose

Methyl D-callipeltose 12 and D-callipeltose 4 were synthesized from D-glucal 5 in 10 and 11 steps, respectively. The synthesis features an azide displacement reaction of an α-nosyloxy ketone 7 and a highly diastereoselective C-methylation of α-azido keton

An aldol-based approach to the asymmetric synthesis of L-callipeltose, the deoxyamino sugar of L-callipeltoside A.

[reaction: see text] The L-callipeltose subunit of L-callipeltoside A has been synthesized in 10 steps and 13% overall yield from D-threonine. The key steps are a highly diastereoselective Felkin anti aldol addition to a methyl ketone and a selective methylation of a secondary alcohol in the presence of a secondary carbamate.
