Synthesis of enones, pyrazolines and pyrrolines with gem-difluoroalkyl side chains
Starting from easily accessible gem-difluoropropargylic derivatives, a DBU-mediated isomerisation affords enones in fair yields with a gem-difluoroalkyl chain. These derivatives were used to prepare pyrazolines and pyrrolines with the desired gem-difluoroalkyl side chain by cyclocondensations in good yields and with excellent stereoselectivity. A one-pot process was also successfully developed ...
متن کاملCascade reactions in total synthesis.
The design and implementation of cascade reactions is a challenging facet of organic chemistry, yet one that can impart striking novelty, elegance, and efficiency to synthetic strategies. The application of cascade reactions to natural products synthesis represents a particularly demanding task, but the results can be both stunning and instructive. This Review highlights selected examples of ca...
متن کاملPreparation of imidazo[1,2-a]-N-heterocyclic derivatives with gem-difluorinated side chains
Using an aerobic oxidative coupling, different new imidazo[1,2-a]-N-heterocycles with gem-difluroroalkyl side chains have been prepared in fair yields by the reaction of gem-difluoroenones with aminopyridines, -pyrimidines and -pyridazines. Condensed heterocycles of this type play an important role as key core structures of various bioactive compounds. Further, starting with a chloroimidazopyri...
متن کاملSynthesis of a Novel Kind of Amphiphilic Graft Copolymer with Miktoarm Star-Shaped Side Chains
ReceiVed January 17, 2008 ReVised Manuscript ReceiVed February 21, 2008 Introduction. In recent years, much attention is paid to the synthesis of copolymers with different compositions and chain architectures, such as linear, grafted, comb-shaped, star-shaped, hyperbranched, and dendrimeric chains with the purpose to establish architecture-property relationships in bulk and in solution. Of thes...
متن کاملSynthesis of cyclic polyesters: effects of alkoxy side chains in salicylaldiminato tin(II) complexes.
A new class of salicylaldiminato tin(II) catalysts having different alkoxy side chains has been developed. The ligands were modified to have different lengths and flexibilities such as –(CH2)2– (2a), –(CH2)3– (2b), –(ortho-C6H4)CH2– (2c) and –(CH2)2–O–(CH2)2– (2d). Complexes 2a, b were characterized crystallographically revealing a more constrained environment around the metal in complex 2a. Th...
