Discovery and SAR studies of novel GlyT1 inhibitors
摘要:
Inhibition of the glycine transporter GlyTl is a potential strategy for the treatment of schizophrenia A novel series of GlyTl inhibitors and their structure-activity relationships (SAR) are described. Members of this series are highly potent and selective transport inhibitors which are shown to elevate glycine levels in cerebrospinal fluid. (c) 2007 Elsevier Ltd. All rights reserved.

By use of the strategy of ortho‐lithiation, p‐bromoanisole and p‐iodoanisole were ortho‐metalated using ortho‐lithiodimethylbenzylamine as the metalating agent. No halogen exchange was noted during these same conditions. These studies add to the emerging evidence of a hitherto unidentified acidifying effect on the proton(s) ortho‐ to a directing metalation group by both a p‐iodo and a p‐bromo substituent

A new class of cobalt catalytic system for asymmetric hydrogenation of ketones was herein reported, involving the development of novel ferrocene-based secondary phosphine oxide ligands. An unusual P–O bidentate coordination pattern with cobalt was confirmed by an X-ray diffraction study. The bichelating tetrahedral cobalt(II) complexes afforded high reactivities (up to 99% yield) and good to excellent
Catalytic regioselective Friedel-Crafts acylation of an array of anisoles/arenes with various acid chlorides using 5-20 mol % of magnetic nanopowder CuFe2O4 is reported. Unlike the conventional Friedel-Crafts reactions, which are catalyzed by moisture sensitive homogeneous catalysts/promoters, the nanopowder CuFe2O4 catalyst is moisture insensitive and the product/ketone-catalyst isolation is easily achieved using the magnetic properties of CuFe2O4.
