Synthesis and reduction reactions of pyridones and 5-acyl-2-methoxypyridines
Bisset, Alexander A.,Dishington, Allan,Jones, Teyrnon,Clarkson, Guy J.,Wills, Martin
, p. 7207 - 7220 (2017/09/12)
The synthesis of a series of pyridones, from their 2-hydroxypyridine or 2-methoxypyridine precursors, is described, along with studies into their reductions to saturated heterocycles. A number of 5-acylpyridones were prepared and were evaluated as substrates for asymmetric transfer hydrogenation prior to conversion to saturated heterocycles. The enantioselective reduction of 5-acetyl-1-benzylpyrimidine-2,4(1H,3H)-dione is also described.

(Chemical Equation Presented) Looping the lupin: A general synthetic strategy for the construction of the lupin alkaloids has been defined and involves sequential formation of the N1-C10 and C6-C7 bonds, which are common to compounds of this class of natu
A short synthesis of (±)-cytisine
Botuha, Candice,Galley, Carl M. S.,Gallagher, Timothy
, p. 1825 - 1826 (2007/10/03)
The synthesis of racemic cytisine 1 has been completed using (i) N-selective alkylation of 6-bromopyridone with bromide 6 and (ii) Pd(o) mediated intramolecular a-arylation of lactam 8 as key steps to achieve rapid assembly of the tricyclic core skeleton of the lupin alkaloids.
Construction of Hydroxylated Alkaloids (+/-)-Mannonolactam, (+/-)-Deoxymannojirimycin, and (+/-)-Prosopinine through Aza-Annulation

The aza-annulation of β-enamino carbonyl substrates with acrylate derivatives provides an efficient and convenient route for the regioselective construction of δ-lactams.This two-step ring-forming sequence involved initial generation of the benzyl enamine through either a condensation or conjugate addition reaction with BnNH2, followed by aza-annulation with acryloyl chloride or acrylic anhydride.Controlled by the rigid framework of the intermediate lactam, introduction of ring substituents was accomplished with high relative stereoselectivity.The carbonyl functionality, which was necessary to direct the regioselectivity of the aza-annulation reaction, was then transformed into a protected hydroxyl substituent through Baeyer-Villiger oxidation.The resultant δ-lactam product was used as a valuable intermediate in the synthesis of three natural products.Subsequent modification of this δ-lactam gave the naturally occurring α-mannosidase inhibitors (+/-)-mannonolactam and (+/-)-deoxymannojirimycin, while synthesis of the alkaloid (+/-)-prosopinine was accomplished through homologation of the lactam carbonyl.
