Abstract
A short, two-step approach to the synthesis of diazepane or diazocane systems, based on a Ugi multicomponent reaction followed by a subsequent intramolecular SN2 reaction was studied. 1-sulfonyl tetrahydrobenzo[e]-1,4-diazepin-1-ones 1 were obtained in very high yield through a Ugi multicomponent reaction followed by Mitsunobu cyclization. On the other hand, aliphatic 1-sulfonyl 1,4-diazepan-5-ones 2 could be obtained employing different cyclization conditions (sulfuryl diimidazole). A similar approach toward diazocane rings using hydroxamates as nucleophiles was less successful, affording only O-cyclized adducts or unexpected side products. A mechanistic explanation of the observed outcomes is proposed.

Abstract
Naturally occurring macrocycles often exhibit remarkable biological activities and, therefore, constitute an attractive starting point for diversity-oriented synthesis for lead discovery in drug development. Multicomponent reactions have been used for the introduction of chemical diversity in strategies towards macrocycle libraries, mostly by combinational synthesis of a linear precursor combined with a subsequent macrocyclization reaction. The Ugi reaction in particular may be used for the macrocyclization itself as well, and a library of natural product-like macrocycles can be constructed in a single step from simple precursors. The efficiency and versatility of both strategies is immense and is exemplarily illustrated by the construction of small libraries of cyclopeptide alkaloid derivatives and biaryl ether macrocycles. The syntheses of the latter compound group are examples of multiple multicomponent macrocyclizations including bifunctional building blocks (M3iB3 or MiB), of which the Ugi-MiBs and their variations are discussed in more detail.

Abstract
[reaction: see text] A novel three-component synthesis of tetrahydrofuro[2,3-c]pyridines from readily accessible starting materials is described. Simply heating a toluene solution of an aminopentynoate, an aldehyde, and an alpha-isocyanoacetamide in the presence of ammonium chloride provided the 4,5,6,7-tetrahydrofuro[2,3-c]pyridines in good to excellent yield. The fused ring system is produced in this one-pot process by the concomitant formation of five chemical bonds.

Abstract
A novel multicomponent synthesis of 5-aminooxazole starting from simple and readily available inputs is described. Thus, simply heating a methanol solution of an aldehyde 3, an amine 4, and an alpha-isocyanoacetamide 5 provided the 5-aminooxazole (1) in good to excellent yield. The reaction of 1 with alpha,beta-unsaturated acyl chloride 13 lead to the formation of pyrrolo[3,4-b]pyridin-5-one (2) in a single operation. A triple domino sequence, acylation/IMDA/retro-Michael cycloreversion, is involved in this new scaffold-generating reaction. After the observation that ammonium chloride can significantly accelerate the oxazole formation in toluene, a one-pot four-component synthesis of 2 is developed.
