Thermal rearrangement of 2-alkynyl alkanedithioates
TL;DR: In the presence of catalytic amounts of C2H5N(i-C3H7)2 to 1,3-dithiole derivatives (5) possibly via allenyl alkanedithioates R1R2CHC(S)SC(R4)CCHR3 although these intermediates have not been isolated as mentioned in this paper.
Journal ArticleDOI
Ketene S,N‐acetals from thioamides
TL;DR: In this article, the authors obtained good yields by treatment of thioamides RCH2C(= S) (NR'2) with one equivalent of potassium amide in liquid ammonia and subsequent alkylation with alkyl bromides.
Journal ArticleDOI

TL;DR: In this paper, the 1,2,3-trienyl ethers RR′CCCCHOCH3 have been metallated in the 1 position by lithium amide and butyllithium, and subsequently alkylated or hydroxy-alkylated.
Journal ArticleDOI
25-hydroxydihydrotachysterol2 an innovative synthesis of a key metabolite of dihydrotachysterol2
TL;DR: In this paper, a new synthesis of 25-hydroxydihydrotachysterol 2 was described using a chiral Wittig reagent, and the synthesis was carried out in 18 steps.
