  Synthesis and androgen receptor affisity of steroidal methylsulfonylforans and a menthylsulfonylthiophene

  摘要：

  Syntheses of the unsubstituted steroidal [3,2-b]furan (3a), thiophene (3b) and [2,3-b]furan (24) are described. Lithiation of the THP ethers 18a and 18b followed by the reaction with methyl disulfide and deprotection gave the 5'-methylsulfide derivatives 19a and 19b. Oxidation of the sulfides and ethynylation provided the compounds 2a and 2b. Swern oxidation of the [2,3-b]furan 24 with DMSO/TFAA/diisopropylethylamine resulted in oxidation to the 17-ketone and introduction of a 5'-methylthio group to give 25. Ethynylation at C-17 followed by oxidation of the sulfide group provided the product 27. 5'-Methylsulfonyl[3,2-b]furanosteroid 2a bound to the rat ventral prostate androgen receptor. However, the corresponding thiophene 2b and the [2,3-b]furan 27 lacked affinity for the receptor.
