Humic substances (HS) were isolated from the sediments of Lobos Pond (Argentina) using mild conditions to preserve their native structure. The HS (humic and fulvic acids) were characterized by means of elemental analysis and FTIR spectroscopy. Also a

Synthesis of 6-thia analogs of the natural neurosteroid allopregnanolone

Autor: Fernando Javier Duran, Alberto A. Ghini, Gerardo Burton, Héctor Coirini

Publikováno v: Tetrahedron. 62:4762-4768

A procedure is described for the preparation of 6-thiapregnanes in five steps from pregnenolone via a 5-oxo-7-iodo-secopregnane intermediate. The 6-thiasteroid obtained was converted into 6-thia-allopregnanolone and its sulfoxide and sulfone derivati
