I found the field of Chemistry very interesting. Saw the article Synthetic Entry to Polyfunctionalized Molecules through the [3+2]-Cycloaddition of Thiocarbonyl Ylides published in 2019.0. SDS of cas: 93-02-7, Reprint Addresses Magauer, T (corresponding author), Leopold Franzens Univ Innsbruck, Inst Organ Chem, Innrain 80-82, A-6020 Innsbruck, Austria.; Magauer, T (corresponding author), Leopold Franzens Univ Innsbruck, Ctr Mol Biosci, Innrain 80-82, A-6020 Innsbruck, Austria.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde
Here we present a comprehensive study on the [3+2]-cycloaddition of thiocarbonyl ylides with a wide variety of alkenes and alkynes. The obtained dihydro- and tetrahydrothiophene products serve as exceptionally versatile intermediates providing access to thiophenes, dienes, dendralenes, and vic-quarternary carbon centers. The use of high-pressure conditions enables thermally unstable, sterically encumbered or moderately reactive substrates to undergo the cycloaddition under mild conditions, thereby increasing the yield by up to 58%. In addition, we showcase its utility by the formal syntheses of the pharmaceuticals NGB 4420 and tenilapine.
