A side reaction occurring in the Wolff-Kishner reduction of certain acetylenic aldehydes (as e.g. 2 or 10) is shown to be a synchronous thermal process. The mechanism of this reaction is discussed in terms of the rules of the conservation of orbital symmetry.

The invention relates to a method of altering hypothalamic function in an individual. The method comprises nasally administering a human vomeropherin, e.g. a 19-nor pregnane steroid, or a pharmaceutical composition containing a vomeropherin, such that the vomeropherin binds to a specific neuroepithelial receptor. The steroid or steroids is/are preferably administered in the form of a pharmaceutical composition containing one or more pharmaceutically acceptable carriers. Other embodiments of the invention include pharmaceutical compositions containing the steroids.
