Peixoto, Philippe A. published the artcileFormal Asymmetric Synthesis of Echinopine A and B, Application of (S)-4-Benzylthiazolidine-2-thione, the main research area is echinopine sesquiterpene enantioselective formal synthesis cyclization palladium catalyst; Diels Alder reaction echinopine sesquiterpene enantioselective formal synthesis.
The asym. formal synthesis of (+)-echinopines A and B was accomplished. Particularly noteworthy were the cascade construction of the [5,6,7]tricyclic ring system I (R = SiMe2CMe3) from the acyclic enyne precursor (2Z,6R,7R)-H2C:CHCH(CH2CH2CH:CH2)CH(OSiMe2CMe3)(CH2)2CH:CHCO2Me through a palladium-catalyzed cycloisomerization with subsequent intramol. Diels-Alder reaction, and the strategic application of a late-stage ring contraction of epoxy ketone II (R = SiMe2CMe3).
Angewandte Chemie, International Edition published new progress about Cyclization. 171877-39-7 belongs to class thiazole, name is (S)-4-Benzylthiazolidine-2-thione, and the molecular formula is C10H11NS2, Application of (S)-4-Benzylthiazolidine-2-thione.
