The reaction of 20-hydroxyecdysone with methyl or ethyl iodide or allyl bromide in a lithium-ammonia solution results in stereospecific 7α-alkylation to give 7α-methyl-, 7α-ethyl-, and 7α-allyl-14-deoxy-Δ(8(14))-20-hydroxyecdysones, respectively. By catalytic hydrogenation (Pd-C/MeOH), the 7α-allyl derivative was converted to(More)
