Chemistry is traditionally divided into organic and inorganic chemistry. category: thiazolidine, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 19771-63-2
A convenient synthesis of chiral oxazolidin-2-ones and thiazolidin-2-ones and an improved preparation of triphosgene
Oxazolidin-2-ones and thiazolidin-2-ones are conveniently prepared by condensation of L-serine, L-threonine and L-cysteine, respectively with triphosgene. The corresponding methyl esters may be subsequently obtained by quenching the reaction mixture with methanol, without prior need for the isolation of the free acids. An improved procedure for preparation of triphosgene using an internal cooling system is described.
