PROCEDURE
实验过程
Monohydrogenate dl-3-methoxy-6-methyl-17,17-ethylenedioxy-13-ethylgona-1,3,5(10),8,14-pentaene (15.3 g) in benzene (300 cc) in the presence of 2% Pd/CaCO3 (5.0 g). Filter, remove the benzene under reduced pressure and recrystallize from 95% ethanol (110 cc) to yield the dl-3-methoxy-6-methyl-17,17-ethylenedioxy-13-ethylgona-1,3,5(10),8-tetraene (11.0 g), m.p. 122°-124°, diamond shaped plates, λ max. EtOH 280 mμ (ε15,140).
