Abstract Sodium dithionite has been effectively used in the reduction of steroidal ketones and enones with remarkable selectivity and high yields under phasetransfer catalysis (PTC) conditions to give alcohols and ketones respectively. An application of these selectivities is demonstrated by reducing an important steroid intermediate 16-dehydropregnenolone acetate to pregnenolone acetate in very high
