  • Various phenol derivatives were synthesized in a one-pot reaction from MBH acetates and sodium diethyl oxalacetate via a [4C+2C] cyclization protocol. In addition, some pyridine derivatives could also be synthesized using the same starting materials, by isolating the $S_N2^{\prime}$ reaction intermediate and performing the cyclization with $NH_4OAc$.
