After purging air through the mixture of aldehydes and amino alcohols and microwaved the reaction mixture at 50°C for minutes gave the corresponding oxazinanes, and oxazolidines in excellent yields.
Amino acid precursors in protected amino alcohol form are important synthons that can be used as building-blocks for the hemisynthesis of non-natural amino acids.Serine can be used as a common starting material for th...

Two novel N-dichloroacetyl oxazolidines were synthesized with a simple, mild and convenient method in good yields. The compounds were Characterized by IR, 1^H NMR and elemental analysis. The preliminary biological tes...
Two N-dichloroacetyl oxazolidines were synthesized with a simple, mild and convenient method. All the compounds were characterized by IR, HNMR and elemental analysis. The 1 preliminary biological test showed that the ...
Ring inversion of eight substituted 2-phenyl-4,4-dimethyloxazolidines in o-dichloro- benzene-d_4 was studied by ~H DNMR.Very high inversion barriers((?)G_c(?)=86.7—93.4 kJ·mol^(-1)) were found for these oxazolidine ...
