Chemistry of Pyrrolizines; Reactions with Cyanogen Bromide and Trifluoroacetic Anhydride
-Interaction of the pyrrolizine 3 with cyanogen bromide in a tetrahydrofuran/water mixture affords addition to the enamine double bond with formation of 5 which can be aromatized to 6 by silica gel. Reaction of 6 with cyanogen bromide in the same solvent mixture yields the indoline 8a which structure is proved in a chemic/d way by conversion of the product into the aldehyde 8(1. The different r...
متن کاملMetal-free radical oxidative alkoxycarbonylation and imidation of alkanes.
A metal-free radical oxidative carbonylation of alkanes is demonstrated, yielding esters and imides by means of di-tert-butylperoxide as an oxidant. Various alkanes, alcohols and amides were compatible in this system generating the desired carbonyl products in up to 86% yields. We proposed a plausible radical cross-coupling process based on the preliminary mechanistic studies.
متن کاملCyanogen Bromide Cleavage and Partial Amino Acid
When samples containing homoserine and homoserine lactone Porcine growth hormone has been cleaved with cyanogen were analyzed, the short column and the first part of the long bromide and the resulting fragments separated by gel filtracolumn (until glutamic acid emerged) were run at 50” instead of tion. The amino acid sequences of the amino-terminal the usua1 55”* Under these conditions homoseri...
متن کاملFlash Preparation of Carbenoids: A Different Performance of Cyanogen Bromide
Cyanogen halides are known substances for the cyanating reaction. There are a few evidences for bromination reaction too. On the other hand carbenes are known as very important substances due to their remarkable reactions. Unfortunately carbenes at room temperature are very unstable and there is not a simple method for preparation of them. In most cases the isolation is not possible. We have re...
متن کاملIsolation of cyanogen bromide cleavage peptides from myoglobins.
The chemical cleavage of apomyoglobins by the cyanogen bromide procedure1 has provided frag ments suitable for sequence analysis2; 3 and for studies of physical 4~6 and immunochemical pro perties 7. Offord 8 has used a peptide obtained from the cyanogen bromide cleavage of ribonuclease in studies aimed at the semi-synthesis of a protein. The purpose of this report is to present condi tions t...
