Mycangimycin is a eicosa-heptenic acid containing an unprecedented 3,5-disubstituted-1,2-dioxolane ring with promising anti-fungal and antimalarial activity. Most reported methods to prepare 1,2-dioxolanes are targeting 3,3,5,5-tetrasubstituted or 3,3,5-trisubstituted 1,2-dioxolanes. Thus, some methods for synthesizing these unusual 3,5-disubstituted 1,2-dioxolanes were investigated. The most promising approach was the use of a Kulinkovich reaction followed by an oxidative ring opening of the cyclopropanol with Co(acac)2to reach the peroxy-hemiketal structure. Successive triflic acid mediated silane reduction of the corresponding peroxy-hemiketal afforded the expected 3,5-disubstituted-1,2-dioxolane ring. Through our studies, some unprecedented rearrangements of 1,2-dioxolane rings were observed, which will be discussed in this Letter. Finally, two saturated analogues of mycangimycin were synthesized.

Effect of deuteration on the metabolism and clearance of some pharmacologically active compounds - Synthesis and in vitro metabolism of deuterated derivatives of dronedadrone
Schofield, Joseph,Brasseur, Denis,De Bruin, Beatrice,Vassal, Thierry,Klieber, Sylvie,Arabeyre, Catherine,Bourrie, Martine,Sadoun, Freddy,Fabre, Gerard
, p. 504 - 512 (2014/03/21)
The synthesis and in vitro metabolism studies of a family of specifically deuterated derivatives of dronedarone are described. Metabolic stability and clearance of the parent compound are not sensitive to deuterium substitution, irrespective of the position of the heavy label. Copyright
