  • A One-Pot Method for the Efficient Conversion of Aryl- and Acyl-substituted Methyl Alcohols into Chlorides
    作者:Gaifa Lai、Ping-Zhong Tan、Pallab Ghoshal

    日期:2003.1.6
    Abstract A one-pot and efficient conversion of aryl- and acyl-substituted methyl alcohols into the corresponding chlorides is described, which involved tosylation with tosyl chloride and triethylamine in the presence of a catalytic amount of 4-(dimethylamino)pyridine (DMAP) in CH2Cl2, followed by methanol-facilitated replacement of the tosylates with chloride. This mild method is readily amenable to

  • Process Improvements in the Synthesis of Corticosteroid 9,11β-Epoxides
    作者:Xiaoyong Fu、Chou-Hong Tann、T. K. Thiruvengadam
    DOI:10.1021/op0102013
    日期:2001.7.1
    Corticosteroid 9,11 beta -epoxides are key intermediates in the preparation of pharmaceutically important compounds such as betamethasone, mometasone, beclomethasone, and dexamethasone. A new process for the 9,11 beta -epoxide was developed using a PCl5-mediated regioselective dehydration of II alpha -hydroxysteroid to form the corresponding Delta (9,11) double bond. The olefin is then converted into 9 alpha ,11 beta -bromoformate by treatment with 1,3-dibromo-5, 5-dimethyl hydantoin (DBH) in DMF and subsequently cyclized to produce the desired 9,11 beta -epoxide upon treatment with NaOH. Major process-related impurities such as 21-OH-Delta (9,11)-triene, 21-OH-Delta (11,12)-triene, 21-Cl-Delta (9,11)-triene, and beta -epoxide-21-cathylate as well as 11 beta -Cl are all eliminated or minimized. This new process has been implemented in our manufacturing facility in full-scale production and proved to raise the overall yield and the quality of the product dramatically compared to the existing process.
