A versatile method for the solid phase synthesis of oxazolidin-2-ones is described. A resin bound phenolic group was treated with (Β±)-epichlorohydrin followed by opening of the epoxide ring with sodium azide. The resulting 1-azido-3-aryloxypropan-2-ol was treated with p-nitrophenylchloroformate and

β¦ Synopsis
1,3-Oxazolidines 9 were synthesized by using a solid support. Regioselective ring opening of resin-bound epoxy ether 3 with ammonium chloride followed by nucleophilic substitution with sodium azide gave azido alcohol 7. Reduction of 7 provided 1-amino-2-alkanol 6, which was treated with various aldehydes and acyl chlorides or isocyanates to aord the corresponding 1,3-oxazolidines immobilized on Wang resin. Oxidative cleavage with DDQ from the solid support yielded 1,3-oxazolidines as a mixture of 10 (cis) and 11 (trans).
