Sonochemically assisted 2,3-dideoxygenation and skeletal rearrangement of ecdysteroid derivatives

•Effectiveness of ultrasound in ecdysteroid 2,3-dideoxygenation was demonstrated.•Semipinacol rearrangement was observed in the case of 2,3-dimesyloxypoststerone.•2,3-Didesoxy-Δ2(3)-poststerone and its (8R)-13(14 → 8)-abeo-isomer were synthesized.•The method could be utilized for synthesis of rare n...
