Tius, Marcus A.,Busch-Petersen, Jakob,Yamashita, Mason
, p. 4219 - 4222 (1998)
The cationic cyclopentannelation reaction provides an unconventional but highly efficient strategy for the synthesis of unsaturated prostanoids and their analogs.
A Close-to-Aromatize Approach for the Late-Stage Functionalization through Ring Closing Metathesis
Lozhkin, Boris,Ward, Thomas R.
, (2021/04/27)
An efficient approach for the synthesis of monosubstituted aromatic compounds relying on a ring-closing metathesis followed by spontaneous 1,2-elimination is presented. The efficiency for late-stage functionalization is highlighted in various solvents (up to 920 TON). This approach is compatible with strained cycles and other multiple bonds in the substrate.

N-Methoxy-N-methylcyanoformamide, a Highly Reactive Reagent for the Formation of β-Keto Weinreb Amides and Unsymmetrical Ketones
Nugent, Jeremy,Schwartz, Brett D.
, p. 3834 - 3837 (2016/08/16)
A rapid and straightforward synthesis of the new and highly reactive reagent N-methoxy-N-methylcyanoformamide from trimethylsilyl cyanide and N-methoxy-N-methylcarbamoylimidazole, is reported. This reagent enables the one-pot preparation of β-carbonyl Wei
One-Pot Synthesis of O -Aryl Carbamates
Varjosaari, Sami E.,Suating, Paolo,Adler, Marc J.
, p. 43 - 47 (2015/12/26)
A simple, versatile, one-pot procedure for the synthesis of substituted O-aryl carbamates has been developed, and a protocol is henceforth described. N-Substituted carbamoyl chloride is formed in situ and subsequently reacted with a substituted phenol, avoiding the direct manipulation of sensitive reactants. This procedure offers an economical and efficient route to many compounds of interest.
Directing group enhanced carbonylative ring expansions of amino-substituted cyclopropanes: Rhodium-catalyzed multicomponent synthesis of N-heterobicyclic enones
Shaw, Megan H.,Melikhova, Ekaterina Y.,Kloer, Daniel P.,Whittingham, William G.,Bower, John F.
supporting information, p. 4992 - 4995 (2013/05/22)
Aminocyclopropanes equipped with suitable N-directing groups undergo efficient and regioselective Rh-catalyzed carbonylative C-C bond activation. Trapping of the resultant metallacycles with tethered alkynes provides an atom-economic entry to diverse N-heterobicyclic enones. These studies provide a blueprint for myriad N-heterocyclic methodologies.
Synthesis and evaluation of carbamate prodrugs of a phenolic compound

A series of carbamates of the phenolic compound 1 were prepared and evaluated in vivo as its prodrug. Each carbamate was orally administered to rats, and plasma concentrations of the parent compound 1 were measured with the passage of time. We judged which carbamate was suitable for the prodrug of 1 from both the AUC value of 1 and absence of the carbamate in plasma. The AUC value of 1 after oral administration of 2b was approximately 40-fold higher than that for an administration of 1, and the bioconversion from 2b to 1 was excellent. As a whole, di-substituted carbamates resulted in higher plasma concentrations of 1 than did mono-substituted ones. However di-substituted carbamates were almost always detected in plasma. As a result, we found that the ethycarbamoyl derivative 2b demonstrates the best prodrug property in this series.
Palladium-catalyzed coupling reactions of N-methoxy-N-methylcarbamoyl chloride for the synthesis of N-methoxy-N-methylamides
Murakami, Masahiro,Hoshino, Yujiro,Ito, Hajime,Ito, Yoshihiko
, p. 163 - 164 (2007/10/03)
A new synthetic method of N-methoxy-N-methylamides is developed. The palladium-catalyzed coupling reaction of N-methoxy-N-methylcarbamoyl chloride furnished N-methoxy-N-methylamide in moderate to good yield, wherein a carbonyl equivalent was appended to s
