Abstract
Reaction of 1-hydroxycarbazole-2-carbaldehydes 1 with phenacyl bromide yielded 2-benzoyl-10 H -furo[2,3- a ]carbazoles 2 , whereas the reaction with ethyl bromoacetate yielded 1-oxo-1,2-dihydro[1,4]oxazino[2,3,4- jk ]carbazole-4-carbaldehyde ( 4 ). The reaction of 1 with ethyl acetoacetate and also with diethyl malonate yielded the pyranocarbazoles 6 and 7 , respectively. All the products were characterized by spectral and analytical means. Plausible mechanisms of product formation are proposed.
