Preparation, alkylation, and olefination reaction of 5-phosphonomethyl- 3-methylisoxazole
Lee, Shi Yong,Lee, Bum Sung,Oh, Dong Young
, p. 2027 - 2029 (1999)
5-Diethylphosphonomethyl-3-methylisoxazole (1) was synthesized by two methods, 1) cycloaddition of nitrile oxide and 2) nucleophilic reaction of the 3,5-dimethylisoxazole anion. This phosphonoisoxazole 1 was alkylated and olefinated by reaction of its ani
