Design, synthesis, and structure–activity relationships of a series of novel N-aryl-2-phenylcyclopropanecarboxamide that are potent and orally active orexin receptor antagonists
Herein we describe the design, synthesis, and structure–activity relationships (SARs) of a novel phenylcyclopropane series represented by 7 and 33b as antagonists of orexin 1 and orexin 2 receptors. With 4 serving as the initial lead for the development of orexin antagonists, exploration of SAR resulted in improved binding affinity for orexin 1 and orexin 2 receptors. Among the synthesized compounds

Provided are methods for aqueous isolation of depolymerized lignin in high yield from a lignin-containing biomass composition, comprising positioning a lignin-containing biomass composition into a flowthrough thermal reactor chamber to provide for passage of an aqueous fluid therethrough, contacting the lignin biomass composition with the aqueous fluid under elevated temperature conditions sufficient to provide for lignin release and depolymerization, flowing the aqueous fluid through the reactor chamber under the elevated temperature conditions, to provide an output aqueous fluid comprising released depolymerized lignin, and collecting the depolymerized lignin. Particular aspects further comprise hydrogenation and/or hydrodeoxygenation (HDO) of the released depolymerized lignin with a catalyst or catalyst system for deconstruction of the released depolymerized lignin into lower molecular weight reactive lignin moieties and oligomers amenable for subsequent removal of oxygen to produce hydrocarbon fuels and/or chemicals and/or compounds. Systems for practicing the methods are also provided, along with highly purified depolymerized lignin.

methoxy group. The regioselectivity, which is high in nonpolar media (benzene), is lower in polar solvents (CH2Cl2) and (CH3CN). The synthetic potential of this transformation, exemplified by the preparation of compounds 29 (Scheme 3) and 32 (Scheme 4), is considerably extended by applying milder methods for the phosphate hydrolysis and by using the reagent couple P(OCH3)3/trimethylsilyl chloride, which
