The synthesis of (RS)-[2-H] glycine by the reduction of a dilute solution of glyoxylic acid in aqueous ammonia by sodium borodeuteride is described. under which the principal side product of the reduction, iminodiacetic acid, is minimized.
A number of 1-alkyl-4-prop-2-ynylthioquinolin-2(1H)-one derivatives are synthesised by the phase transfer catalyzed reaction of 1-alkyl-4-marcaptoquinolin-2(1H)-ones with different prop-2-ynylic halides. These are then regioselectively cyclised in refluxing chlorobenzene to give hitherto unreported
## Abstract Heating of hexahydroโ5__H__โpyrrolo[2,1โ__c__][1,4]benzodiazepineโ2,5,11โtrione in boiling phosphoryl chloride led to a rearranged product like 3,5โdichlorobenzo[__h__][1,6]naphthyridine. This structure was established from Xโray diffraction analysis.
