Abstract

Abstract Ketal ester 9 has been prepared in five steps from methyl levulinate 4 (scheme 1). The propionate 1, diol 2 and (±) frontalin 3 were prepared from ester 9 employing the routes shown in scheme 2, 3 and 4 respectively. The branched chain alkenes 13 and 20 were prepared conveniently from the primary alcohols 11 and 10 following the procedure of S. Wolff. Triethyl phosphonopropionate 7 has been prepared by methylating ...
