A nasal preparation comprising a compound represented by the formula:
wherein Ring A is an optionally substituted 5- or 6-membered aromatic heterocyclic ring, Ring B is an optionally substituted 5- or 6-membered aromatic homocyclic or heterocyclic ring, R1 is a hydrogen atom, a hydroxyl group or a lower alkyl group, and n is 0 or 1, which has an Na-H exchange inhibiting activity, or a salt thereof exhibits excellent bioabsorbability and an Na-H exchange inhibiting activity superior to that of an oral preparation, thus being useful as a prophylactic and/or therapeutic agent for ischemic heart diseases such as myocardial infarct and arrhythmia.
of α,β-unsaturated methyl ketone/nitro compounds from benzylic amines through an oxidation–aldol/Henry reaction is reported. The reaction proceeded well by using MCPBA as oxidant and CuCl2·2H2O as catalyst. A variety of functionalized α,β-unsaturated methyl ketone/nitro compounds were assembled in moderate yields by application of this catalytic one-pot reaction.
