SYNTHESIS OF POTENTIAL ECDYSTEROID PRECURSORS FROM Δ7,22 STEROLS

Two routes for the conversion of 5α-cholest-7-ene-3β-ol (11) into 7, which has the typical ecdysteroid substitution pattern in rings B, C, and D, have been developed.Making use of one of the methods, 5,6-dihydroergosterol (31) was converted into the 38, p
