Abstract
The triazolobenzodiazepine as a cyclic imine was employed in a variety of Joullié-Ugi reactions, and three new families of unique triazolobenzodiazepine connected to carboxamide and tetrazole products were synthesized via a three-component reaction of the cyclic imine and isocyanides with each species of a carboxylic acid/water/TMSN3 under mild conditions in high yields. Furthermore, triazolobenzodiazepine imine was used in an interesting strategy based on the modified Ugi reaction (pseudo-Joullié-Ugi reaction) of cyclic imines with an isocyanide and acetylenedicarboxylates under catalyst-free conditions for the synthesis of triazolobenzodiazepine-fused pyrroles. Mechanistic investigation reveals that triazolobenzodiazepine-fused pyrroles have been generated via a surprising route. Significantly, the use of triazolobenzodiazepine in the Joullié-Ugi, azido-Joullié-Ugi, and pseudo-Joullié-Ugi reactions of a broad scope of biological scaffolds occurred under mild, simple conditions without any catalyst.

Abstract
The three-component reaction of isoquinolines, dialkyl acetylenedicarboxylates, and 5,6-unsubstituted 1,4-dihydropyridines in acetonitrile at room temperature afforded functionalized isoquinolino[1,2-f][1,6]naphthyridines in good yields and with high diastereoselectivity. More importantly, the formal [2 + 2] cycloaddition reaction of dialkyl acetylenedicarboxylates and 5,6-unsubstituted 1,4-dihydropyridines in refluxing acetonitrile gave unique 2-azabicyclo[4.2.0]octa-3,7-dienes as major products and 1,3a,4,6a-tetrahydrocyclopenta[b]pyrroles as minor products via further rearrangement.

Abstract
An efficient three-component reaction to access spiro[benzo[a]acridine-12,4'-imidazolidine]-2',5'-dione derivatives has been developed through the ring-opening and recyclization process of isatins and dehydroxylation of 2-naphthol, which is different from their conventional reaction modes. Experimental observations suggest that p-toluenesulfonic acid is the key factor that promotes the success of this synthetic strategy. The research provided a novel approach for the construction of spiro compounds from isatins and 2-naphthol in organic synthesis.

Abstract
A novel and unexpected route for synthesizing pyrrole-fused dibenzoxazepines/thiazepines has been designed based on a modified Ugi reaction of cyclic imines with isocyanides and acetylenedicarboxylates under catalyst-free conditions. Mechanism investigation indicates that this process is carried out through the production of zwitterion species (Huisgen's 1,4-dipole), which is a key intermediate in the chemoselectivity of products. This Huisgen's 1,4-dipole is trapped in situ with isocyanides and a variety of pyrrole-fused dibenzoxazepines/thiazepines are synthesized in a simple one-pot operation with high yields and chemoselectivity. This strategy opens a new route in Ugi reactions (pseudo-Joullié-Ugi reaction) for the synthesis of pyrrole-fused heterocycles as special pharmaceutical scaffolds.

Abstract
In the presence of tetrabutylammonium bromide (TBAB), the cycloaddition reaction of phenacylmalononitriles with dialkyl but-2-ynedioates in acetonitrile at room temperature resulted in 3,3-dicyano-5-hydroxy-5-arylcyclopent-1-ene-1,2-dicarboxylates in high yields. More importantly, the DABCO-promoted domino reaction of two molecules of each phenacylmalononitrile and dialkyl but-2-ynedioate in acetonitrile at room temperature afforded unique multifunctionalized carboxamide-bridged dicyclopentenes in moderate to good yields and with high diastereoselectivity.

Abstract
1,4-Dipolar cycloaddition has emerged as a powerful tool for the synthesis of various cyclic compounds. In the present work, 1H-pyrrole-2,3-diones are proposed as new dipolarophiles for 1,4-dipolar cycloaddition. Their [4 + 2] cycloaddition with dipoles generated from dimethyl acetylenedicarboxylate and pyridine was found to proceed regioselectively affording spiro[pyrido[2,1-b][1,3]oxazine-2,3'-pyrroles] as diastereomeric mixtures which exist in rapid equilibrium in solution. It was established that this phenomenon of rapid epimerization is a characteristic of other similar spiropyrido[2,1-b][1,3]oxazines and even related spiroquinolizines, which was demonstrated by the investigation of related products of previously reported, and reproduced in this work, 1,4-dipolar cycloaddition reactions.
