Chiral pool based approach for the synthesis of bio-active lactones and 1,2-aminoalcohols
Synthesis of 10-membered bioactive lactone microcarpalide (I), (2S,3R)-2-aminododecan-3-ol (II), and Xestoaminol C (III) from inexpensive chiral pool sources such as tartaric acid and L-(+)-alanine was described. The ... -
Enantiospecific approaches to Valeranes,Cyperanes,Bicyclo[4.3.1] Decanes and Spiro[5.5] Undecanes
Enantiospecific syntheses of (+)-valerane 2, (-)-valeranone 1, 5-epicyperanes 107 and 123, and cyperane 134 have been accomplished. To begin with, (R)-carvone 38 was converted into the allyl alcohol 40 in three steps. An ... -
Studies on the metabolism of structural analogues of a potent hepatotoxin, R-(+)- pulegone, a monoterpene ketone, in both mammalian and microbial systems
Pennyroyal oil from Mentha pulegium has been widely used as a fragrance component, a flavoring agent, and also as an herbal medicine to terminate pregnancy. R-(+)-pulegone (I), a monoterpene ketone, is the major constituent ... -
