A Novel and Highly Stereoselective Approach to Aza-Spirocycles. A Short Total Synthesis of 2-epi-(¡À)-Perhydrohistrionicotoxin and an Unprecedented Decarboxylation of 2-Pyrones

(Matrix Presented) A novel and highly stereoselective synthesis of aza-spirocycles is described. An application of this methodology is illustrated as a short and concise total synthesis of 2-epi-(¡À)-perhydrohistrionicotoxin with high diastereomeric control at the aza-spirocenter. An unprecedented decarboxylation of the 2-pyrone ring is observed in this total synthesis effort.

Safety of 3-Methyldihydrofuran-2,5-dione, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4100-80-5, name is 3-Methyldihydrofuran-2,5-dione. In an article£¬Which mentioned a new discovery about 4100-80-5

Reactions of Trialkylsilyl Trifluoromethanesulfonates, VIII. – Synthesis of O-(Trimethylsilyl)ketene O,N-Acetals, 2,5-Bis(trimethylsiloxy)pyrroles, -furans, and -thiophenes

Ketene O,N-acetals 3, 4, 6, 8 are obtained from N,N-diarylcarboxamides and N-acetylheterocycles 5, 7 by silylation with trimethylsilyl triflate (2) in the presence of triethylamine.Analogous reactions of carboxamides 9 and N-acyllactams 11 yield the ketene O,N-acetals 10, 12.Succinimides 13, succinic anhydrides 20, and succinic thioanhydrides 22 are doubly silylated by 2 to give the 2,5-bis(trimethylsiloxy)heterocycles 14, 21, 23. 2,5-Bis(trimethylsiloxy)furan (21a) reacts with aldehyde acetals and orthoesters 24 catalyzed by 2 to yield 2,3-disubstituted succinic anhydrides 25.

Synthesis and anticancer activity of 4-aza-daurinol derivatives

Daurinol, a natural aryl naphthalene lactone, has been reported to have antiproliferative activity against various cell lines, and has also been shown to be efficacious in an in vivo xenograft mouse model. In this study, we tried to discover a new scaffold that enables both rapid structure-activity relationship study of daurinol and scalable synthesis of active compounds. 4-Aza-daurinol, a bioisosterism-based scaffold of daurinol, was designed and 17 analogues were synthesized and evaluated against five representative cancer cell lines. Among them, the 2,3-dihydrobenzo[b][1,4]dioxinyl derivative was found to be the most potent and showed similar activity and tendency as daurinol.
