A synthesis new aryl alicyclic tricarboxylic acids bearing two carboxyl groups at either cyclohexane or norbornane fragment and one carboxyl group at the benzene ring was devel-oped. Tricarboxylic acids of this type are promising monomers for the synthesis of hetero-cyclic polymers.

A new and convenient approach has been deviced for the practical synthesis of structurally robust, four different pseudoenantiomeric amino Tf-amido organocatalysts with the unique cis- and trans-substituted 1,2-cis-cyclohexanediamine structures. These pse

The addition of benzene to cis-4-cyclohexene-1,2-dicarboxylic anhydride yielded c-2-benzoyl-t-5-phenyl-r-1-cyclohexanecarboxylic acid (72%), or in another reaction, the 4-phenyl isomer (67%). With bifunctional reagents, saturated tricyclic or partially sa

In the introduction, a brief survey is given of the main types of fused-skeleton saturated six-membered 1,3-heterocycles serving as model compounds in our earlier investigations and as starting compounds in the present studies.The synthesis and conformational analysis of aryl-substituted fused-skeleton saturated 1,3-oxazines and of aryl-substituted hetero-condensed saturated isoindolones are treated. cis-trans isomerization in the saturated isoindolone moiety of the resulting tricyclic, tetracyclic and pentacyclic systems is discussed in connection with the ring-closure reactions of cis- and trans-1,2-disubstituted 1,2- and 1,3-difunctional alicyclic compounds to give alicycle-fused six-membered 1,3-heterocycles.The cycloaddition reactions of dihydro-1,3 and 3,1-oxazines and the conformations of the alicycle-fused tetrahydrooxazine-azetidinone derivatives obtained are presented.Methods are given for the preparation of saturated thiazolo- and thiazinoquinazolinones.Unambiguous, mainly one-pot syntheses for the preparation of 1,3-heterocycles by a retro Diels-Alder method are discussed.
