Fujiwara, Shinichi; Cadou, Romain; Yamaoka, Yousuke; Takasu, Kiyosei; Yamada, Ken-ichi published an article in 2015, the title of the article was Hydrostannylation-cross-coupling strategy for the stereoselective synthesis of alkylidenemalonates and related α,β-unsaturated esters.SDS of cas: 14602-86-9 And the article contains the following content:
A method for the stereoselective synthesis of alkylidenemalonates and related α,β-unsaturated esters by hydrostannylation-cross coupling process was developed. Regio- and diastereoselective Pd-catalyzed hydrostannylation of propiolate derivatives provided α-alkoxycarbonyl (E)- and (Z)-vinylstannanes which were then converted into resp. alkylidenemalonates by the Stille coupling reaction with corresponding chloroformates. A one-pot process was also realizable for the Pd-catalyzed reactions. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).SDS of cas: 14602-86-9
The Article related to alkylidenemalonate alpha beta unsaturated ester preparation, vinyl stannane preparation chloroformate stille coupling, propiolate tributylstannane hydrostannylation regioselective diastereoselective and other aspects.SDS of cas: 14602-86-9
