From vicinal azido alcohols to Boc-amino alcohols or oxazolidinones, with trimethylphosphine and Boc2O or CO2 was written by Ariza, X.;Pineda, O.;Urpi, F.;Vilarrasa, J.. And the article was included in Tetrahedron Letters in 2001.Electric Literature of C11H21NO3 This article mentions the following:
A practical solution to the problem of converting directly 1,2-azido alcs. to Boc-amino alcs., without recourse to catalytic hydrogenation, involves the use of Me3P/Boc2O in THF (or CH2Cl2) and aqueous NaOH at rt (90-98% yields). The same azido alcs. can be converted in one-pot to the corresponding oxazolidinones with Boc2O/DMAP/Me3P or even better with CO2 and Me3P under basic catalysis (91-96% yields). In the experiment, the researchers used many compounds, for example, tert-Butyl (trans-2-hydroxycyclohexyl)carbamate (cas: 121282-70-0Electric Literature of C11H21NO3).
tert-Butyl (trans-2-hydroxycyclohexyl)carbamate (cas: 121282-70-0) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Electric Literature of C11H21NO3
