    摘要: 2,5-dihydrothiazoles are prepared by reacting aza-alkylene-dienes with sulfur at relatively low temperatures for example below about 160.degree. C. Where the reaction is carried out at relatively higher temperature, for example above about 160.degree. C., such as 160.degree. to 250.degree. C., 4,5-dihydrothiazoles are formed. In addition 2,5-dihydrothiazoles can be converted to 4,5-dihydrothiazoles by heating them to temperatures above about 160.degree. C.

    摘要: The present invention discloses novel 6-acylamino-2,2-dimethyl-3-phosphonopenams and certain lower alkyl esters thereof possessing antibacterial activity, methods for their production, and intermediates therefor; the production comprises the steps of reacting 6-triphenylmethylamino-2,2-dimethylpenam-3-carboxylic acid with lead tetraacetate to form the corresponding 3-acetoxy compound, the latter is converted to .alpha.-triphenylmethylamino-5,5-dimethyl-3-thiazoline-2-acetic acid which is condensed with dimethyl phosphite to produce .alpha.-triphenylmethylamino-5,5-dimethyl-4(0,0-dimethylphosphono)-thiazolidine-2-acetic acid which is cyclized to 6-triphenylmethylamino-2,2-dimethyl-3-(0,0-dimethylphosphono)penam and the latter is subsequently deblocked and acylated.
