Abstract
The reactive 1:1 intermediate produced in the reaction between cyclohexyl isocyanide and dialkyl acetylenedicarboxylates was trapped by arylsulfonamides to yield highly functionalised stable ketenimines under mild reaction conditions in fairly good yields.

Abstract
The adduct produced in the reaction between alkyl isocyanides and dialkyl acetylenedicarboxylates was trapped by furan-2-carboxylic acid arylidene-hydrazides to afford highly functionalised ketenimines in good yields. The reaction is characterised by mild conditions, high selectivity, and tolerance to various functional groups.

Abstract
The first study of the reaction between nucleophilic carbenes and ketenimines is reported. The interaction of thiazole and benzothiazole carbenes with ketenimines proceeded in a chemospecific and stereoselective manner to produce thiazole- and benzothiazole-spiro-pyrrole derivatives generally in good yields. The reaction was proposed to proceed via a tandem nucleophilic addition of carbene to the C=N bond of ketenimine followed by a stepwise [3+2] cycloaddition of the 1,3-dipolar intermediate with the C=C bond of ketenimine. This reaction provides a powerful protocol for the construction of novel polyfunctional thiazole-spiro-pyrrole or benzothiazole-spiro-pyrrole compounds that are not readily accessible by other methods.
