The Stereochemical Configuration of DL-@-Fluoromalic Acid*
The synthesis of two isomers of nn-b-fluoromalic acid has been reported in a previous publication from this laboratory (1). On the basis of elementary analysis and equivalent weights, the two isomers were undoubtedly the threo and erythro isomers of nn-fi-fluoromalic acid. However, at that time it was not possible to make a definite assignment of stereochemical configuration to the two isomers....
متن کاملSynthesis and Hydrolytic Degradation of Substituted Poly(DL-Lactic Acid)s
Non-substituted racemic poly(DL-lactic acid) (PLA) and substituted racemic poly(DL-lactic acid)s or poly(DL-2-hydroxyalkanoic acid)s with different side-chain lengths, i.e., poly(DL-2-hydroxybutanoic acid) (PBA), poly(DL-2-hydroxyhexanoic acid) (PHA), and poly(DL-2-hydroxydecanoic acid) (PDA) were synthesized by acid-catalyzed polycondensation of DL-lactic acid (LA), DL-2-hydroxybutanoic acid (...
متن کاملConvenient method for synthesis of a carbon-14 analogue of DL-Phenyl alanine
DL-Phenyl alanine labeled with carbon-14 in the α-position has been synthesized from ethyl[2-14C] acetate as part of a 6-step sequence.
متن کاملEfficacy of DL-methionine hydroxy analog free acid and DL-methionine as methionine sources for pigs.
Two experiments were conducted to evaluate the efficacy of dietary DL-methionine hydroxy analog-free acid (MHA-FA, 88%) compared with DL-methionine (DLM, 99%) as Met sources in pigs. In Exp. 1, a total of 245 crossbred pigs (initial BW of 6.4 kg [SD = 0.5]) were allotted to 7 treatments in 7 replicates for an experimental period of 28 d. The basal diet (BD) was formulated to contain 17.5% CP an...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
