## Abstract New pyrrolo[2,1‐__a__]isoquinolines were obtained by two one‐pot procedures via 1,3‐dipolar cycloaddition between the isoquinolinium N‐ylides and symmetrical acetylenic dipolarophiles, avoiding the formation of dihydro intermediates. For structural comparison, the dihydro derivatives ob

## Abstract A new method for the estimation of torsion barriers and its application to conformational analysis is presented. This method, the ToBaD method (method of the torsion barrier derivative), makes use of crystal structure data. It is based on the assumption that the conformation of a compou
The urazole 3 derived from 2,3-dimethylindole and PTAD has been found to be converted readily to the unusually stable azomethine imine 5 with t-butylhypochlorite followed by elimination of HCI. This azomethine imine has been shown to serve as a carbonyl-equivalent in a number of aldol-type condensat
