Savie is a biodegradable surfactant derived from vitamin E and polysarcosine (PSar) developed for use in organic synthesis in recyclable water. This includes homogeneous catalysis (including examples employing only ppm levels of catalyst), heterogeneous catalysis, and biocatalytic transformations, including a multistep chemoenzymatic sequence. Use of Savie frequently leads to significantly higher yields than do conventional surfactants, while obviating the need for wastegenerating organic solvents.
New technology is reported that enables Negishi couplings to be run under sustainable, far greener conditions. Thus, ppm Pd-containing nanoparticles (NPs) have been developed that catalyze couplings in recyclable water under very mild conditions. These heterogeneous reactions involve loadings of Pd of typically only 2500 ppm (0.25 mol %). Highly functionalized aromatic and heteroaromatic bromides readily participate, including examples taken from the Merck Informer Library indicative of the functional group tolerance associated with these couplings. Direct comparisons with existing literature routes are made. Very low residual levels of Pd in newly formed products are to be expected, as determined by ICP-MS. The reagent involved has been extensively characterized via DLS, TEM, cryo-TEM, and EDX measurements.
Herein, we report
the discovery of the first selective and CNS
penetrant mGlu7 PAM (VU6027459) derived from a “molecular
switch” within a selective mGlu7 NAM chemotype.
VU6027459 displayed CNS penetration in both mice (Kp =
2.74) and rats (Kp= 4.78), it was orally bioavailable in
rats (%F = 69.5), and undesired activity at DAT was ablated.
Savie is a biodegradable surfactant derived from vitamin E and polysarcosine (PSar) developed for organic synthesis in water. This includes homogeneous catalysis (including examples employing only ppm levels of catalyst), heterogeneous catalysis, and biocatalytic transformations, including a 3-step, 1-pot chemoenzymatic sequence. Savie frequently enables significantly higher yields than conventional surfactants, while obviating the need for environmentally egregious organic solvents.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
