Burkhardt, Immo; Lauterbach, Lukas; Brock, Nelson L.; Dickschat, Jeroen S. published an article in 2017, the title of the article was Chemical differentiation of three DMSP lyases from the marine Roseobacter group.Computed Properties of 168297-86-7 And the article contains the following content:

Dimethylsulfoniopropionate (DMSP) catabolism of marine bacteria plays an important role in marine and global ecol. The genome of Ruegeria pomeroyi DSS-3, a model organism from the Roseobacter group, harbors no less than three genes for different DMSP lyases (DddW, DddP and DddQ) that catalyze the degradation of DMSP to di-Me sulfide (DMS) and acrylate. Despite their apparent similar function these enzymes show no significant overall sequence identity. In this work DddQ and DddW from R. pomeroyi and the DddP homolog from Phaeobacter inhibens DSM 17395 were functionally characterized and their substrate scope was tested using several synthetic DMSP analogs. Comparative kinetic assays revealed differences in the conversion of DMSP and its analogs in terms of selectivity and overall velocity, giving addnl. insights into the mol. mechanisms of DMSP lyases and into their putatively different biol. functions. The experimental process involved the reaction of (S)-4-Isopropyl-5,5-dimethyloxazolidin-2-one(cas: 168297-86-7).Computed Properties of 168297-86-7

On June 30, 2000, Bew, Sean P.; Davies, Stephen G.; Fukuzawa, Shin-Ichi published an article.COA of Formula: C8H15NO2 The title of the article was Kinetic resolution of α-acetoxy carboxylic acids with homochiral SuperQuats. And the article contained the following:

Preliminary investigations focused on the kinetic resolution of (±)-O-acetyl mandelic acid chloride with iso-Pr SuperQuat and iso-Pr Evans’ homochiral auxiliaries. The addition of 2 equiv of the acid chloride to the lithium salts of the auxiliaries (SuperQuat and Evans’) at -100° in THF afforded the N-acyl auxiliaries in high chem. yields (95 and 89%) and d.e.’s of 66 and 40%, resp. Using the same mandelic acid chloride but incorporating SuperQuat auxiliaries derived from (S)-phenylglycine and (S)-phenylalanine gave the N-acyl SuperQuats in 86 and 90% yield and d.e.’s of 66 and 30%, resp. Replacing the Ph group in the O-acetyl mandelic acid chloride with a Bu, tert-Bu, or cyclohexyl group changed the d.e. significantly when kinetically resolved with iso-Pr SuperQuat. The yields were all similar, i.e., ∼90%, but the d.e.’s varied considerably, with values of 20, 50, and 82%, resp. Attempted kinetic resolution of α-methoxy-phenylacetyl chloride using the lithium salt of iso-Pr SuperQuat revealed a diastereoselectivity of 45%, significantly lower than that obtained with the corresponding α-acetoxy carboxylic acid chlorides. The experimental process involved the reaction of (S)-4-Isopropyl-5,5-dimethyloxazolidin-2-one(cas: 168297-86-7).COA of Formula: C8H15NO2
