When an additive is used to replace a certain amount of cement, a concrete pore structure becomes dense. Thus, it results in inhibiting the penetration of chlorine ions and suppressing corrosion of reinforcing bars. However, the pH level of the concr

Determination of analogs of sildenafil and vardenafil in foods by column liquid chromatography with a photodiode array detector, mass spectrometry, and nuclear magnetic resonance spectrometry
Autor: Jae Sung Pyo, Janghyun Park, Deukjoon Kim, Sung Won Kwon, Tae Hyung Yoon, Hye Kyoung Jeong, Sangaeh Park, Dong Mi Choi
Publikováno v: Journal of AOAC International. 91(3)
Two analogs of sildenafil and vardenafil in food were detected by column liquid chromatography (LC) with a photodiode array detector. They were isolated by preparative LC; their structures were established by mass spectrometry and nuclear magnetic re

Substrate-controlled formal synthesis of (+)-laurenyne by a chemoselective chelation-controlled alkylation strategy
Autor: Gukwha Cheon, Janghyun Park, Deukjoon Kim, Hyunjoo Lee, Hyoungsu Kim, Sanghee Kim, Byungsook Kim
Publikováno v: Scopus-Elsevier
A substrate-controlled formal synthesis of (+)-laurenyne has been accomplished featuring a highly stereoselective chemoselective chelation-controlled amide enolate alkylation for synthesis of the α,α'-syn-bis-alkene without resorting to use of a ch
