โฆ Synopsis
Monofluoroacetyl and difluoroacctylsteroidal furans were prepared by selective reductive dehalogenation of chlorofluom and chlomdifluomacetyl inmm&iates with sodium formaldehyde sulfoxylate. WC have mcently qcatedl the synthesis of S-mthylsulfonyl[3,2-b]~dat fumn (1) and the androgen receptor activity of this compound. In order to explore the suuctum-activity relationship of this series of compounds, we have introduced a number of other electron withdrawing substituents at 5' position of the

The preceding paper (1) ha8 described that the oxidation of mercaptans to diaulfidee by means of diethyl azodicarboxylate is extremely promoted by triphenyl phoaphine rithout being changed itself. A tautomeric pair of thiol and thiocarbonyl structures exists in a thiourea. Thus, the re-
