Synthesis of Alkylpyrroles by the Sodium Borohydride Reduction of Acylpyrroles
Greenhouse, Robert,Ramirez, Coral,Muchowski, Joseph M.
, p. 2961 - 2965 (2007/10/02)
N-Unsubstituted alkylpyrroles are obtained by the reduction of the corresponding acylpyrroles with sodium borohydride in boiling 2-propanol.This reaction was demonstrated to proceed via the pyrrolylalkylcarbinol and was extended to the synthesis of a branched chain alkylpyrrole 25 from the tertiary alcohol 24.
Compounds with Bridgehead Nitrogen. 42 - 1H NMR and Stereochemistry of Isomeric 6a-Methylperhydroindolobenzoxazines and the Position of Conformational Equilibrium in Perhydropyrrolooxazine
Crabb, Trevor A.,Newton, Roger F.,Rouse, Janet
, p. 113 - 116 (2007/10/02)
The 1H NMR parameters of the NCH2O protons in the spectrum of perhydropyrrolooxazine show its existence in solution at room temperature in the O-inside cis-fused conformation, rel-(3aS,6aS,6bR,10aS,11aS)6a-Methylperhydroindolobenzoxazine and rel-(3aS,6aS,6bS,10aR,11aS)-6a-methylperhydroindolobenzoxazine are shohn to adopt cis- and trans-fused conformations, respectively, for the corresponding bicyclic moiety.
