Preparation of D-Cycloserine and 13C-Labeled D-Cycloserine
摘要:
D-Cycloserine (DCS), a second stage drug for the treatment of tuberculosis, is synthesized in 19.8% overall yield from DL-serine methyl ester. This synthetic route gives both enantiomers of cycloserine via a corrected and improved one pot resolution procedure using D- and L-tartaric acids. The route is used to synthesize a C-13-labeled derivative for use in biological studies.

Though haemangioma of nose is a common tumor, those arising from the paranasal sinuses are not very common. Very few cases have been reported. Because of its rarity under the backdrop of existing literature we are reporting our present case.
