Selective Alkylation of Amines with Alcohols by Cp*–Iridium(III) Half-Sandwich Complexes
摘要:
[(CpIr)-Ir-star(Pro)Cl] (Pro = prolinato) was identified among a series of Cp-star-iridium half-sandwich complexes as a highly reactive and selective catalyst for the alkylation of amines with alcohols. It is active under mild conditions in either toluene or water without the need for base or other additives, tolerates a wide range of alcohols and amines, and gives secondary amines in good to excellent isolated yields.

This invention relates to the use of potent potassium channel blockers or a formulation thereof in the treatment of glaucoma and other conditions which leads to elevated intraocular pressure in the eye of a patient. This invention also relates to the use of such compounds to provide a neuroprotective effect to the eye of mammalian species, particularly humans.
A compound represented by, e.g. the formula (I):
[wherein X, Y, Z, and W each independently represent optionally substituted methine; A, B, and D each independently represent —C(O)—, etc.; Q represents a methine or a nitrogen; and R represents the formula (II-1), optionally substituted with lower alkyl, etc.;
(wherein R
6
represents a lower alkyl, etc; and R
7
and R
8
each independently represents a lower alkyl, etc.)] or a pharmaceutically acceptable salt of the compound. The compounds and salt have antagonistic activity against a histamine H3 receptor or inverse agonistic activity against a histamine H3 receptor. They are useful in the prevention or treatment of metabolic diseases, circulatory diseases, or neurotic diseases.
