Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge.5306-85-4, Name is (3R,3aR,6S,6aR)-3,6-Dimethoxyhexahydrofuro[3,2-b]furan, molecular formula is C8H14O4, belongs to pyrrolines compound, is a common compound. In a patnet, author is Demir, Ayhan S., once mentioned the new application about 5306-85-4, Quality Control of (3R,3aR,6S,6aR)-3,6-Dimethoxyhexahydrofuro[3,2-b]furan.
Selective one-pot synthesis of substituted pyrrole-3-phosphonates from alpha-cyanomethyl-beta-ketoesters
A one-step synthesis of 5-alkoxypyrrole-3-phosphonates is presented starting from suitable alpha-cyanomethyl-beta-ketophosphonates. The key step in the synthesis involves a one-pot addition and heteroannulation sequence. The zinc perchlorate-catalyzed addition of alcohols to the nitrile carbon of alpha-cyanomethyl- beta-ketophosphonates followed by annulation furnished 5-alkoxypyrrole-3-phosphonates. The addition-annulation process is carried out in the presence of water and 4,5-dihydro-5-oxo-1H-pyrrole-3-phosphonates (pyrrolinones) are obtained in good yields. (C) 2007 Elsevier Ltd.
