Synthesis of heterocyclic compounds with adamantane-like cage structures consisting of phosphorus, sulfur, and carbon

Abstract

The synthesis of novel adamantane-like cage compounds consisting of phosphorus, sulfur, and carbon atoms was developed. We examined the reaction of a variety of acetophenone derivatives with P4S10 in refluxing benzene. A novel noradamantane-like cage compound was also synthesized, when the reaction of 2'-methoxyacetophenone with P4S10 was performed in refluxing toluene. In addition, by using the adamantane-like cage compound, 4,4'dimethoxybenzophenone and N,N-dimethylbenzamide were successfully transformed into the corresponding thioketone (98%) and benzothioamide (89%), respectively.

“…Crystallization is an indispensable technique for solid separation and purification, and solubility data plays a crucial role. − In the existing literature, however, there are only DMBP-related reactions and other fundamental investigations but almost no solubility data. , Therefore, it is essential to supplement and improve DMBP solubility data.…”

“…Derivatives that include heteroatoms have been synthesized, in addition to the well-known aza-(AZADO and hexamethylenetetramine) [31][32][33][34] and oxo-derivatives (tetrodotoxin) [35]. Other derivatives involving C/As/O (arsenicin A) [36], C/N/S (tetramethylenedisulfotetramine) [37], P/S (phosphorus pentasulfide) [38], P/N [39], and C/P/S [40] have also been described.…”
