AI Article Synopsis
- * A crucial step in this synthesis involved the coupling of a diene sulfone and a tetrahydropyranyl aldehyde.
- * The synthetic sample exhibited a specific rotation that was opposite to that of the natural product, indicating that the natural product's absolute configuration may need to be reconsidered.
Article Abstract
This paper describes a seven-step synthesis of the proposed structure for chaunopyran A produced by cocultivation of a sp. and . This synthesis included a coupling of a diene sulfone and a tetrahydropyranyl aldehyde as a key step. The sign of the specific rotation value of the synthetic sample was opposite that of the natural product, suggesting that the absolute configuration of the natural product should be revised.
