3-tert-butylpropynal,chemoselectively at the aldehyde group to give the corresponding Schiff bases in almost quantitative yield [2].We recently proposed a new highly efficient approach to heteroelement-containing propynals via microwave-assisted solid-phase reaction which ensured direct transformation ...
The article focuses on the study about the reaction of the 3-trimethylsilyl-2-propyn-1-al(I) with nitromethane in acetonitrile in the presence of 5 moI percent of diazabicyclooctane at room temperature. The researchers isolated 4-trimethylsilylethynyl-4H-pyran-3,5-dicarbaldehyde(III) instead ...
The invention herein is directed to a process for the preparation of ethyl 3S-amino-4-pentynoate which involves treating 3-(trimethylsilyl)-2-propynal with L-phenylglycinol in toluene to produce 伪S- 3-(trimethylsilyl)-2-propynylidene amino!benzenethanol; reacting 伪S- 3-(trimethylsilyl)-...
Trimerization of 3-Trimethylsilyl-2-propyn-1-al into 4-Trimethylsilylethynyl-4H-pyran-3,5-dicarbaldehydeWe recently showed the possibility to perform one-pot direct conversion of organoelemental alpha-acetylene alcohols R_3MC ident to CCH_2OH into 1,3-enynes R_3MC ident to CCH=CR~1R~2 ...
It was shown that the aldehyde and amine ratio affects the concurrent trimerization of 3-trimethylsilyl-2-propyn-1-al into 4-(trimethylsilylethynyl)-4H-pyran-3,5-dicarbaldehyde involving one molecule of water as a nucleophile. Two plausible mechanisms of 1,2-dihydropyridine and 4H-pyran cascade ...
