摘要: The synthesis of 4-oxo- and 4-anti-formyl-8,10,12,13-tetraoxapentacyclo[5.5.1.0(2,6).0(3,11).0(5,9)]tridecanes has been accomplished. Ozonolysis of compounds 10a,b and 12a-c in dichloromethane at -78 degrees C followed by reduction with dimethyl sulfide gave the title compounds, 4-oxo-tetraoxa-cages 11a,b and 14a-c, in moderate yields. Ozonolysis of the endo-syn isomers 15a,b and 18a,b under the same reaction conditions gave 4-anti-formyl-tetraoxa-cages 17a,b and 20a,b, respectively. (C) 1997 Published by Elsevier Science Ltd.
