    摘要: The invention thus provides a process for obtaining the preferential replacement by isotopes, of at least one of the hydrogen atoms selected from the group consisting of those attached to the .alpha.- or .alpha.'-carbon atoms in a compound containing the structural moiety (I) ##STR1## which comprises the steps of oxidizing the compound to the corresponding sulfoxide or sulfone which contains the corresponding structural moiety (II) ##STR2## wherein in the sulfoxide n is 1 and in the sulfone n is 2, effecting the isotopic replacement by a known method of said at least one hydrogen atom, and reducing the resultant isotope-labelled sulfoxide or sulfone to the correspondingly labelled compound containing the structural moiety (I).

    摘要: Provided is a production method for a cis-QMF, which has a low environmental burden and is industrially advantageous. Specifically provided is a production method for a cis-type 2-alkylspiro(1,3-oxathiolane-5,3′)quinuclidine hydrochloride, including: reacting a cis-trans isomer mixture of 2-alkylspiro(1,3-oxathiolane-5,3′)quinuclidine with p-nitrobenzoic acid; resolving the resultant product to produce a cis-type 2-alkylspiro(1,3-oxathiolane-5,3′)quinuclidine p-nitrobenzoate; and converting the p-nitrobenzoate into a hydrochloride.

    摘要: Novel dry skin remedies useful for treatment dry skin, containing as the active ingredient spiro [oxathiolane-quinuclidine] derivatives represented by general formula (I) or acid addition salts thereof, desirably cis-2-methylspiro [1,3-oxathiolane-5,3'-quinuclidine] hydrochloride. The remedies promote the secretion of sebaceous and sweat glands through oral or parenteral administration to treat dry skin, thus being useful as drugs.
