TL;DR: Three hybrid polymeric iodoplumbates constructed from morpholine and its derivatives, which exhibit a semiconductor nature, and third-order nonlinear optical (NLO) activities can be detected in 1 and 3.
Abstract: Three hybrid polymeric iodoplumbates constructed from morpholine and its derivatives, {(Pb(4)I(15))[(Mph·H)(3)(Mph·1.5H)(2)]}(n)(1), {(edm-H(2))(Pb(3)I(8))]·2DMF}(n)(2), {(edm-H(2))[(dmp)(Pb(4)I(12))]˙2DMF}(n) (3) (Mph = morpholine, edm = ethylenedimorpholine, dmp(2+) = N,N'- dispiromorpholinopiperazonium) have been synthesized and structurally determined. In these compounds, morpholine and its derivatives weakly interact with or covalently bond to polymeric iodoplumbates. In 1, hydrogen bonds between (Pb(4)I(15))(7-) clusters and protonized Mph contribute to the formation of a 1-D hybrid chain. In 2, the 1-D [(Pb(3)I(8))](n)(2n-) chain is extended to be a 2-D layer via the edm(2+) ligand by means of Pb-O covalent bonds. Interestingly, the 2-D [(Pb(4)I(12))](n)(4n-) inorganic layer in 3 is concertedly templated by two kinds of organic cations. The above compounds exhibit a semiconductor nature, and third-order nonlinear optical (NLO) activities can be detected in 1 and 3.

TL;DR: A series of diverse glycosyl 1,2-azido alcohols, obtained from readily available carbohydrates, were converted to structurally varied rare and novel sugar derived morpholine fused [5,1-c]-triazoles via a one-pot strategy to affords numerous C- and O-glycosyl bicyclic ring systems with medicinal value via a metal free cycloaddition reaction.
Abstract: A series of diverse glycosyl 1,2-azido alcohols, obtained from readily available carbohydrates, were converted to structurally varied rare and novel sugar derived morpholine fused [5,1-c]-triazoles via a one-pot strategy. After incorporating a propargyl functionality at the hydroxyl group of the sugar derived 1,2-azido alcohols, the resulting in situ generated azido–alkyne affords numerous C- and O-glycosyl bicyclic ring systems with medicinal value via a metal free cycloaddition reaction. The structures of all the developed molecules have been elucidated using 1H NMR, 13C NMR, IR and MS spectroscopy.

TL;DR: In this article, a new heterogeneous nanomagnetic catalyst bearing morpholine tags was synthesized and characterized, and its catalytic performance was examined in multicomponent preparation of hexahydroquinolines and 2-amino-4,6-diphenylnicotinonitriles through vinylogous anomeric based oxidation under mild reaction conditions.
Abstract: A new heterogeneous nanomagnetic catalyst bearing morpholine tags was synthesized and characterized. The formation of the nanomagnetic catalyst was fully confirmed by several methods, including Fourier-transform infrared (FT-IR) spectroscopy, energy-dispersive X-ray (EDX) spectroscopy, elemental mapping, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetry/derivative thermogravimetry (TG/DTG), and vibrating-sample magnetometry (VSM). The catalytic performance of the novel nanomagnetic catalyst was examined in multicomponent preparation of hexahydroquinolines and 2-amino-4,6-diphenylnicotinonitriles through vinylogous anomeric-based oxidation under mild reaction conditions. Novel magnetic nanoparticles with morpholine tags promoted synthesis of hexahydroquinolines and 2-amino-4,6-diphenylnicotinonitriles through vinylogous anomeric-based oxidation.

TL;DR: In this paper, a series of alanine oligomers containing solubility-enhancing blocking groups were obtained through the use of 2-methoxy-[2-ethoxy-(2]- acetic acid (MEEA) and morpholine (Mo) as blocking groups for the N- and C-terminal ends, respectively.
