Synthetic Approach to Stemodin (I) - A Novel Stereocontrolled Construction of the Stemodane System by the Successive Intramolecular Diels-Alder Reaction

The synthesis of the A, B, C and ring part 17 of diterpene stemodin (1) from 1,4-cyclohexanedione monoethylene ketal (8) by use of the successive intramolecular Diels-Alder reactions is described.

Pd2+-promoted cyclization in tetracyclic diterpene synthesis highly diastereoselective formal total synthesis of (±)-stemodin

Intramolecular Diels-Alder reaction of the triene 5 and Pd2+-promoted cyclization reaction of the olefinic silyl enol ether of 10 have been utilized as the key steps for a conceptually new, highly diastereocontrolled formal total synthesis of (

Synthetic approach to stemodin-A novel stereocontrolled construction of the stemodane system by the successive intramolecular Diels-Alder reactions

The tetracyclic compound 18, possessing the stemodane skeleton, was synthesized from 1,4-cyclohexanedione monoethylene ketal 7. The key steps, 6→5 and 16→18, involve intramolecular Diels-Alder reaction.
