A new subset of β-(ester)alkyl radicals is presented. It is the first study on the chemistry of β-(alkoxycarbonyloxy)alkyl radicals that fill the gap in the spectrum of the migrating groups in β-(ester)alkyl radical reactions. The change from less nucleofugal (acetate) group to the more nucleofugal (carbonate) group in the spectrum of the migrating group changed the reaction path from rearrangement
Novel bisphosphonate cyclic acetal compounds are disclosed, as well as methods of preparing the compounds, pharmaceutical compositions including the compounds, and administration of the compounds in methods of treating bone metabolism disorders, such as abnormal calcium and phosphate metabolism.
The synthesis of several 3,4-dihydro-4-oxo-2H-1,3-benzoxazine-carboxylic acids is described. The acids resulted from hydrogen carbonate hydrolysis of their corresponding esters which were prepared by condensation of salicylamide with various aldehydes and ketones. The use of certain aromatic aldehydes and ketonescontaining an ortho-carboxy-function led to isoindolobenzoxazine structures.
描述了几种3,4-二氢-4-氧代-2 H -1,3-苯并恶嗪-羧酸的合成。酸是由碳酸氢盐水解其相应的酯产生的,这些酯是通过水杨酰胺与各种醛和酮的缩合反应制得的。某些含有邻羧基官能团的芳族醛和酮的使用导致异吲哚并苯并恶嗪结构。
