摘要

Volume 24, No. 4, 1992 OPPI BRIEFS tion of 2 under standad conditions did not give desired 6 but the previously unreported nitrostyrene 3 in 72% yield. The possibility that nitration gave the known isomer 47 instead was ruled out on the i) C&NO,, NH,, OAc, HOAc ii) HNO,, HOAc iii) 4, Pd (OH) & THF-HOAc basis of comparative melting point and proton NMR data. Synthesis via the second path proceeded by reversal of these steps. Hence, ...
