Tandem aza-Claisen rearrangement and ring closing metathesis reactions: the stereoselective synthesis of functionalised carbocyclic amides [PDF]

open access: yes, 2009
A one-pot, tandem process has been developed for the efficient synthesis of functionalised carbocyclic amides. A substituted cyclopentenyl trichloroacetamide was synthesised using a tandem thermal aza-Claisen rearrangement and RCM process, while an ...

Asymmetric one-pot synthesis of cyclopropanes

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2016
Cycloaddition of the diazoalkanes to electron-deficient olefins (in situ) affords polysubstituted cyclopropanes in high yields (up to 85%). Deprotection of the ketal protecting group provided water-soluble cyclopropane-bearing carbohydrate in good yields.

Room-Temperature Alternative to the Arbuzov Reaction: The Reductive Deoxygenation of Acyl Phosphonates [PDF]

open access: yes, 2010
The reductive deoxygenation of acyl phosphonates using a Wolff−Kishner-like sequence is described. This transformation allows direct access to alkyl phosphonates from acyl phosphonates at room temperature. The method can be combined with acyl phosphonate

One-pot preparation of substituted pyrroles from α-diazocarbonyl compounds

open access: yesBeilstein Journal of Organic Chemistry, 2008
In this work an efficient one-pot synthesis of substituted pyrroles 7a–n is described, which involves the in situ formation of dihydrofurans ethyl 5-butoxy-2-methyl-4,5-dihydrofuran-3-carboxylate (4), 1-(5-butoxy-2-methyl-4,5-dihydrofuran-3-yl)ethanone ...

Hept-6-en-1-yl Furan-2-carboxylate

open access: yesMolbank
This study aims to develop an efficient and green one-pot method for the synthesis of 6-en-1-yl furan-2-carboxylic acid heptyl ester. Initially, using furfural as the starting substrate, hept-6-en-1-yl furan-2-carboxylate was prepared using a one-pot ...

The Regio- and Stereoselective Synthesis of 1,4-Diarylbut-1-en-3-ynes Having Aryl Groups at the Mutual Syn Positions

open access: yesOrganics, 2023
(E)-1-aryl-2,4-bis(trimethylsilyl)but-1-en-3-ynes readily undergo protodesilylation and subsequent aerobic, copper-free Sonogashira cross-coupling with aryl halides to form (E)-1,4-diaryl-2-(trimethylsilyl)but-1-en-3-ynes.
