Neurotrope und psychotrope Substanzen IX. Über basische Ester der 2-(2-Phenyläthyl)benzoesäure und einiger Analoga

Facile Approach for C(sp3)–H Bond Thioetherification of Isochroman

“…Adding more DTBP and extending the reaction time could lead to more product 3s (Table 3, entry 2). Notably, this method may have potential usage in total synthesis 15 (provide alternative access to the unique ortho-bifunctionalized structure). Like isochroman, isochroman-4-one could also furnish this C-S coupling, but the presence of the carbonyl group put a negative effect on the product yield with the thioether 3t (Table 3, entry 5) formed in the yield of 30%.…”

Synthesis and conformational analysis of dibenzodithiocin derivatives

“…1. t Authors to whom correspondence should be addressed (synthesis, J. S.; spectroscopy, P. S.). [d,g] [1,3] dithiocin (2a), representing a new ring system, was isolated as the main component of the remainder of the reaction mixture; it was accompanied by a small amount of the new 2,3,8,9-tetramethoxy derivative of the known 6H,12H-dibenzo [b,f] [ 1,5]…”
