, (2017/12/27)
A preparation method of 1-(2-(4-(chloromethyl)phenoxy)ethyl)azacycloheptane hydrochloride comprises the steps of alkylation, substitution, reduction and chlorination. The preparation method for industrially producing the1-(2-(4-(chloromethyl)phenoxy)ethyl)azacycloheptane hydrochloride allows the final product to be produced from cycloheximide as raw material through alkylation, substitution, reduction and chlorination, the total yield of the four steps reaches about 70%, and the purity is 99%. The method also has the advantages of easiness in obtaining of the reaction raw material, mild conditions, simplicity in treatment, and high yield, and is a method suitable for industrial production.

supporting information, p. 5795 - 5798 (2013/06/27)
Unprotected indoles are prepared with the title method, which has a wide scope for alkynes. Excellent regioselectivity was accomplished for aryl-alkyl and alkyl-alkyl disubstituted acetylenes. This reaction features an unusual 1,2 rhodium migration and ring-contraction-triggered N-N bond cleavage. It allows rapid conversion of the reaction products into several functional molecules.

In an systematic attempt to develop novel Selective Estrogen Receptor Modulators (SERMs), chiral 1-((4-(2-(dialkylamino)ethoxy)phenyl)(2- hydroxynaphthalen-1-yl)methyl)piperidin-4-ols were designed based on an accepted pharmacophore model. Simpler prototypes, viz. racemic 1-((2-hydroxynaphthalen- 1-yl)arylmethyl)piperidin-4-ols, were first synthesized to develop kinetic resolution to pure enantiomers. Simultaneously, a series of racemic 1-((4-(2-(dialkylamino)ethoxy)phenyl)(2-hydroxynaphthalen-1-yl)methyl) piperidin-4-ols were evaluated against estrogen-responsive human MCF-7 breast cancer cells, but the compounds were found to be moderately active. The lack of potency could be due to the molecular bulk resulting in inadequate fit at the receptor. Subsequently, the molecular motif was modified to achiral 1-(4-(2-(dialkylamino)ethoxy)benzyl)naphthalen-2-ols by removing the piperidinol moiety. Bioevaluation of this new series of compounds displayed significantly enhanced cytotoxicity against MCF-7 cells. A representative compound for this series showed estrogen receptor alpha binding activity and the action is that of an antagonist.
