Carbocyclinone-534 is a new antibiotic produced after the metabolism of tapinarof. We identify a biomimetic total synthesis of carbocyclinone-534 in eight steps by taking advantage of an intermolecular Diels-Alder homodimerization/dehydrogenation/intramolecular Diels-Alder cycloaddition cascade. This synthetic sequence provides direct experimental evidence for revealing the biosynthetic pathway of carbocyclinone-534.

Paragraph 0223-0232, (2021/01/29)
The invention discloses a synthesis method of (E)-3,5-dihydroxy-4-isopropyl stilbene, which comprises the following steps: by using a biomass-derived raw material 3,5-dihydroxy-2,4-diethoxycarbonyl ethyl phenylacetate as an initiator, carrying out hydrolysis decarboxylation, isopropylation, condensation, decarboxylation, isomerization and other reaction steps to synthesize the (E)-3,5-dihydroxy-4-isopropyl stilbene. In the invention, the biomass derivative raw materials can be adopted as initiators, operation is easy and convenient, the steps are simple and convenient, functional group protection and deprotection are not needed, and atom economy is good; the intermediate can be put into the next step of reaction without complex separation and purification, so that large-scale preparation is facilitated; and the generated excessive waste acid and catalyst compound can be recycled, so that the cost of the technological process is reduced, the emission is reduced, and the method is greenand environment-friendly.
