Synthesis of a TREN in which the aryl substituents are part of a 45 atom macrocycle
Cain, Matthew F.,Forrest, William P.,Peryshkov, Dmitry V.,Schrock, Richard R.,Mueller, Peter
, p. 15338 - 15341 (2013)
A substituted TREN has been prepared in which the aryl groups in (ArylNHCH2CH2)3N are substituted at the 3- and 5-positions with a total of six OCH2(CH2) nCH=CH2 groups (n = 1, 2
A pH-Responsive DNAsome from the Self-Assembly of DNA–Phenyleneethynylene Hybrid Amphiphile
Albert, Shine K.,Golla, Murali,Thelu, Hari Veera Prasad,Krishnan, Nithiyanandan,Varghese, Reji
, p. 8348 - 8352 (2017)
A pH-responsive DNAsome derived from the amphiphilicity-driven self-assembly of DNA amphiphile containing C-rich DNA sequence is reported. The acidification of DNAsome induces a structural change of C-rich DNA from random coil to an i-motif structure that
Synthesis of chloro-substituted 6H-dibenzo[b,d]pyran-6-one natural products, graphislactone G, and palmariols A and B
Abe, Hitoshi,Horino, Yoshikazu,Imai, Haruka,Jeelani, Ishtiaq,Yonoki, Atsuro
, p. 781 - 788 (2021/08/06)
A palladium-mediated intramolecular aryl–aryl coupling reaction was applied to the total synthesis of the bioactive natural products, graphislactone G (1), and palmariols A (2) and B (3), which possess an unusual chloro-subsutituent on the 6H-dibenzo[b,d]
A Revised Modular Approach to (–)-trans-Δ8-THC and Derivatives Through Late-Stage Suzuki–Miyaura Cross-Coupling Reactions
Bloemendal, Victor R. L. J.,Sondag, Daan,Elferink, Hidde,Boltje, Thomas J.,van Hest, Jan. C. M.,Rutjes, Floris P. J. T.
, p. 2289 - 2296 (2019/04/03)
A revised modular approach to various synthetic (–)-trans-Δ8-THC derivatives through late-stage Suzuki–Miyaura cross-coupling reactions is disclosed. Ten derivatives were synthesized allowing both sp2- and sp3-hybridized cross-coupling partners with minimal β-hydride elimination. Importantly, we demonstrate that a para-bromo-substituted THC scaffold for Suzuki–Miyaura cross-coupling reactions has been initially reported incorrectly in recent literature.
Synthesis method of resveratrol

Paragraph 0039; 0040, (2018/05/03)
The invention provides a synthesis method of resveratrol, and belongs to the technical field of natural product synthesis. The synthesis method comprises the following steps: with 3,5-dimethoxy benzoic acid as a raw material, generating 3,5-dimethoxy benzoyl chloride (12) through an acylating chlorination reaction; generating 3,5-dimethoxy benzamide (13) through an amidation reaction of the (12);generating 3,5-dimethoxyaniline (14) through a Hofmann degradation reaction of the (13); generating 3,5-dimethoxy iodobenzene (15) through a Sandmeyer reaction on the (14); generating 3,5,4'-trimethoxy diphenylethene (31) through a reaction between the (15) and p-methoxystyrene (23), and performing demethylation of the (31) to finally obtain resveratrol (1), wherein total yield is 23.3%. Accordingto the method, the adopted reagent is cheap and easily available, aftertreatment is simple, and two expensive intermediates for Heck reaction are synthesized by adopting cheap raw materials. A new synthesis method is provided for synthesizing resveratrol.
