Reaction of aminothiazole-oximetosylates with thiols
摘要:
The reaction of ethyl 2-(2-aminothiazol-4-yl)-2-tosyloxyiminoacetate and its tritylamino analogue with thiols gave ethyl 2-(5-R-thio-2-amino- or tritylamino-thiazol-4-yl)-2-oxoacetate derivatives. Structures were elucidated by ir, H-1-, C-13-nmr and mass spectroscopy. A reaction mechanism is suggested.
The present invention relates to oligoesters and their use or the creation of additives. Oligoester containing additives and/or oligoesters themselves may be used for formulating pharmaceutical preparations, cosmetics or personal care products such as shampoos and conditioners. These oligoesters are particularly useful for the creation of multi-purpose additives that can impart conditioning, long substantivity and/or UV protection. Individual oligoesters and oligoester mixtures are described.
