Furthernewlinehydrogenation of these N-vinyl-1,2,3-triazoles led to facile synthesis of 1,4,5-trisubstituted Nalkyl-newline1,2,3-triazoles.newlineChapter 2 presents an enolate mediated strategy for the synthesis of N,N-bicyclic pyrazolidinones by a [3+2]-cycloaddition between and#945;-enolizable aldehydes and cyclic azomethinenewlineimines. All the reactions were carried out under DBU or tBuOK catalysis. This chapter expandsnewlinethe scope of enolate mediate click reactions beyond azides to other 1,3-dipoles like azomethinenewlineimines.newlineChapter 3 is an attempt to look at amidines like 1,8-diaza-bicyclo[5.4.0]undec-7-ene (DBU), 1,5-Diazabicyclo(4.3.0)non-5-ene (DBN) and some others in new light not just as catalystsnewlineas used extensively in organ |
