Synthesis of oxygen-containing heterocyclic compounds based on monoterpenoids

The review integrates data on the synthesis of chiral oxygen-containing heterocycles of various structural types by reactions of monoterpenoids with carbonyl compounds. Depending on the structure of the monoterpene and carbonyl components and the catalyst used, these reactions lead to mono-, bi-, tri- or tetracyclic products. The possible reaction mechanisms are discussed and data on the biological activities of the products are given.
