Synthesis of poly-substituted pyrroles starting from the Baylis-Hillman adducts
We synthesized poly-substituted pyrrole derivatives 4a-e, 7a-c and 10a-d from the reaction of phenacyl bromide and the aza-Baylis-Hillman adducts 1a-d or their rearranged derivatives 5a-e. The pyrroles were synthesized via the successive N-alkylation, Mic
Reactivite des N-vinylaziridines fonctionalisees. Synthese de derives des α,β-dehydro α-amino acides
Secondary 2-cyano- and 2-ethoxycarbonylaziridines react with acetylenic compounds and activated vinylic chlorides to gives 2-cyano and 2-ethoxycarbonyl N-vinylaziridines.The nucleophile-catalysed isomerization of these compounds generally gives α,β-dehydr
