Abstract 2,4-Bis (4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson's Reagent) reacts with glycinamides (2a-m) in benzene at 55 ∼ 60°C to give 1,3,2-diazaphospholidin-4-thone-2-sulfides (3a-m). The structure of the products has been confirmed by elementary analyses, NMR, IR, MS and X-ray diffraction. The result of preliminary bioassay indicates that some of the compounds prepared

The present invention relates to a method for preparing optically active N-methylamino acids and/or optically active N-methylamino acid amides by subjecting the cells or treatment products of a microorganism belonging to the
Mycoplana
genus to the hydrolysis with N-methylamino acid amide to give an optically active N-methylamino acid and an optically active N-methylamino acid amide. According to the present invention, optically active N-methylamino acids and optically active N-methylamino acid amides useful as the raw material of pharmaceuticals can be stereoselectively obtained with good efficiency.

A facile and efficient cyclization of N-alkoxy α-halogenoacetamides with N-(2-chloromethyl)aryl amides has been achieved for rapid access to 1,2,4,5-tetrahydro-1,4-benzodiazepine-3-one derivatives (up to 95% yield). The intriguing features of this intermolecular cyclization include its mild reaction conditions and easy handling for scalable synthesis.
