Recently I am researching about INTRAMOLECULAR CARBOSULFENYLATION; SWITCHABLE REGIOSELECTIVITY; ENANTIOSELECTIVE SYNTHESIS; NATURAL-PRODUCTS; BASE; SULFENOFUNCTIONALIZATION; CYCLOADDITION; CYCLIZATION; LACTONES, Saw an article supported by the NSFCNational Natural Science Foundation of China (NSFC) [21871178, 21702135, 21871088]; Chenguang Program – Shanghai Education Development Foundation [16CG22]; Shanghai Municipal Education CommissionShanghai Municipal Education Commission (SHMEC). Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Luo, HY; Dong, JW; Xie, YY; Song, XF; Zhu, D; Ding, TM; Liu, YY; Chen, ZM. The CAS is 78-39-7. Through research, I have a further understanding and discovery of 1,1,1-Triethoxyethane. Category: thiazolidines
A divergent strategy for the facile preparation of various enantioenriched phenylthio-substituted lactones was developed based on Lewis base/Bronsted acid co-catalyzed thiolation of homoallylic acids. The acid-controlled regiodivergent cyclization (6-endo vs. 5-exo) and acid-mediated stereoselective rearrangement of phenylthio-substituted lactones were explored. Experimental and computational studies were performed to clarify the origins of the regioselectivity and enantioselectivity. The calculation results suggest that C-O and C-S bond formation might occur simultaneously, without formation of a commonly supposed catalyst-coordinated thiiranium ion intermediate and the potential pi-pi stacking between substrate and SPh as an important factor in the enantio-determining step. Finally, this methodology was applied in the rapid syntheses of the bioactive natural products (+)-ricciocarpin A and (R)-dodecan-4-olide.
