A Nickel-catalyzed reductive process is described for the directamidation of benzyl and aryl halides using carbodiimides as the amidating agent. Moreover, aryl and benzyl C–O electrophiles such as triflate, acetate, tosylate, trityl ether, and pivalate were converted into amides using this method. The in-situ-generated Ni0 acts as a catalyst for the reaction at room temperature for benzylic substrates

are defined as in the specification, that exhibit activity as nitric oxide synthase (NOS) inhibitors, to pharmaceutical compositions containing them and to their use in the treatment and prevention of central nervous system and other disorders.
The present invention relates to new pharmaceutical uses for compounds that exhibit activity as nitric oxide synthase (NOS) inhibitors. Specifically, it relates to the use of NOS inhibitors, particularly selective neuronal NOS (N-NOS) inhibitors: (a) alone or in combination with another active agent for the treatment of psoriasis; (b) in combination with an antiinflammatory agent for the treatment of inflammatory disorders; (c) in combination with a narcotic analgesic (e.g., opiates such as morphine or demerol) for the treatment of pain; (d) alone or in combination with other active agents for the enhancement of cognition; and (e) alone or in combination with other active agents for the treatment of sleep disorders such as apnea, narcolepsy and insomnia.
The present invention is directed to an organometallic complex and a catalyst composition capable of producing polylactide resins with improved properties at a higher conversion rate, a method of producing the organometallic complex, polylactide resins having enhanced hydrolysis resistance and heat resistance together with superior mechanical properties, a preparation process therefor, and polylactide resin compositions including the same.
