TL;DR: In this article, the four stereoisomers of methyl tetrahydrofuran (2,ylmethyl 2,6-dimethyl), 4-(o-nitrophenyl)-1,4-dihydro-pyridine-3,5-dicarboxilate (furnidipine), have been synthesized and separated by chiral chromatography using Dphenylglycine as chiral stationary phase.
Reaction of 2-bromomethylazoles and TosMIC: A domino process to azolopyrimidines. Synthesis of core tricycle of the variolins alkaloids.
TL;DR: A new reaction of N-protected 2-bromomethylazoles and tosylmethyl isocyanide (TosMIC) leading to the preparation of azolopyrimidines is described, and this domino sequence was used to synthesize the pyrido[3',2':4,5]pyrrolo[1,2-c]pyrimidine core of alkaloids variolins from 4-methoxy-2-methyl

One-pot Graebe-Ullmann synthesis of γ-carbolines under microwave irradiation
TL;DR: One-pot efficient and simple synthesis of γ-carboline derivatives by the Graebe-Ullmann method was conducted in a commercial microwave oven in a few minutes at a low energy level and using erlenmeyer as adequate reaction vessels as mentioned in this paper.

Reaction of imines with N-iodosuccinimide (NIS): unexpected formation of stable 1 : 1 complexes
Isabel Castellote,Maria Moron,Carolina Burgos,Julio Alvarez-Builla,Avelino Martín,Pilar Gómez-Sal,Juan J. Vaquero +6 more
TL;DR: This is the first reported example of a halogen bonding interaction involving the C=N bond and NIS, and the structure of one of these was determined by single-crystal X-ray diffraction.

A new approach to polycyclic azonia cations by ring-closing metathesis.
TL;DR: The ring-closing metathesis reaction of N-vinyl-alpha-(2-styryl)azinium salts, using the Hoveyda-Grubbs catalyst, leads to different tricyclic and tetracyclic azonia cations with moderate to good yields.
