WebHere, we report a sequence whereby triflic anhydride and formic and acetic acids activate the bulk chemical nitromethane to serve as a nitrogen donor in place of azides in Schmidt-like reactions. This protocol further expands the substrate scope to alkynes and simple alkyl benzenes for the preparation of amides and nitriles. WebPterocarpans such as (±)-homopterocarpin (31) have been formed directly and efficiently via titanium(IV)-catalyzed cycloadddition of 2H-chromenes with 2-alkoxy-1,4-benzoquinones. 90 In the final step of the synthesis of 31, triflation of 29 followed by a palladium-catalyzed formate reduction of triflate 30 gave (±)-homopterocarpin in 88% overall yield (Scheme … robert hines jr
