On December 26, 2019, Kotammagari, Tharun K.; Paul, Sayantan; Bhattacharya, Asish K. published an article.Computed Properties of 2873-29-2 The title of the article was Unusual Epimerization in Styryllactones: Synthesis of (-)-5-Hydroxygoniothalamin, (-)-5-Acetylgoniothalamin, and O-TBS-Goniopypyrone. And the article contained the following:
(-)-5-Hydroxygoniothalamin (I, R = H), (-)-5-acetylgoniothalamin I (R = COMe), and (+)-5-hydroxygoniothalamin (II), isolated from the Goniothalamus genus, are synthesized from triacetyl-O-D-glucal by employing the Ferrier reaction, Mitsunobu reaction, and Jones oxidation as key steps. The synthetic procedure also yields the epimers of (-)-5-hydroxygoniothalamin and (+)-5-hydroxygoniothalamin employing acid-mediated transition-metal-free epimerization at C-5 of styryllactones. Further studies reveal that the epimerization is facilitated by the Ph group present on the styryllactones. Also, depending on the dihydroxylation reaction conditions, various analogs of saturated styryllactones are synthesized utilizing oxa-Michael reaction conditions. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Computed Properties of 2873-29-2
