Preparation of homochiral crown ether containing (S)-1-(1-adamantyl)ethane-1,2-diol as a chiral subunit and its enantioselective complexation with an organic ammonium cation
摘要:
Homochiral 1-(1-adamantyl)ethane-1,2-diol(5) was prepared and its absolute configuration was determined to be (S)-(+)-5 by enzymatic and H-1 n.m.r. spectroscopic methods. Using (S)-(+)-5 as a chiral subunit, the homochiral crown ether (+)-18 was synthesized and its enantioselectivity in complexation of methionine methyl ester perchlorate was also examined by the H-1 n.m.r. spectroscopic method.

Alkylation of N,N-dialkylcarboxamides with 1,3-dehydroadamantane has been accomplished for the first time. The reaction involves the C-H bond in the alpha-position with respect to the carbonyl group and provides a convenient one- step preparation of substituted carboxylic acid amides containing an 1-adamantyl substituent and a pharmacophoric group in the amide moiety.
