A novel self-terminated Prins strategy has been developed for the synthesis of 2-substituted tetrahydropyran-4-one derivatives through a condensation of 3-(phenylthio)but-3-en-1-ol with carbonyl compounds in the presence of 5 mol% of Sc(OTf)3 under mild conditions. A few products were subsequently transformed into the corresponding indoles by Fisher-indole synthesis.

7-Hydroxy-3-methoxycadalene, isolated from Zelkova serrata Makino, was confirmed as a biologically active natural compound. In this study, the efficacy of cadalene as an anticancer agent was tested. In order to address the poor physicochemical properties of cadalene, we designed and synthesized glycosylated cadalene derivatives for improved solubility and efficient drug delivery as a potential prodrug. In vitro cell viability assays confirmed that glycosylated cadalenes were less toxic and more soluble than cadalene. In an in vivo xenograft study in mice, the oral administration of glycosylated cadalenes caused a significant reduction in tumor size.

Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 28244-94-2, Name is 4-Methylphenyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranoside, molecular formula is C21H26O9S.

Myrmekioside A, which was isolated from the marine sponge Myrmekioderma sp. as a member of the family of natural mono-O-alkyl-diglycosylglycerols, and which has a strong reversion effect on the tumor cell morphology of ras-transformed cells at 5 mug/mL, was synthesized for the first time in 17 steps and 14% overall yield. The beta-glycosidic linkages in myrmekioside A were successfully constructed by the neighbouring-group-participation approach using trichloroacetimidates and thioglycosides as glycosyl donors. The 2R absolute configuration at C-2 of the glycerol backbone was derived from (S)-1,2-isopropylideneglycerol (8). This synthetic approach may be applicable to the preparation of other myrmekioside analogues featuring different sugars and alkyl chains for further structure-activity relationship studies.
