Publikováno v: Journal of Natural Medicines
In this paper, we review our work in the last 10 years wherein we examined the sulfides in the acetone extracts of garlic (Allium sativum), onion (A. cepa), and Welsh onion (A. fistulosum), obtained and characterized the structures of new sulfides, t

A highly efficient In(OTf)3-catalyzed [3 + 3] annulation of spirocyclopropyl oxindoles with 1,4-di-thiane-2,5-diol
Autor: Zhong-Yan Cao, Jian Zhou, Yong-Jia Hao, Ying Zhou, Yi Gong
Publikováno v: Chinese Chemical Letters. 31:681-684
Spirooxindoles play an important role in drug discovery and development. The development of efficient methods for the synthesis of spirooxindoles from easily available starting materials is of current interest. Herein, we report in detail the In(OTf)

Comparison of the C-H⋯O bonding in two crystalline phases of 1,4-di-thiane 1,1,4,4-tetra-oxide
Autor: Richard L. Harlow, Allen G. Oliver, William J. Marshall, Michael P. Sammes, Jonathan M Baker
Publikováno v: Acta Crystallographica Section E: Crystallographic Communications
Acta Crystallographica Section E: Crystallographic Communications, Vol 75, Iss 5, Pp 576-579 (2019)
The structures of two crystalline phases of 1,4-di­thiane-1,1,4,4-tetra­oxide have been determined and found to have similar local C—H⋯O hydrogen-bonding arrangements in spite of differences in the mol­ecular packing.
The crystal structur

Asymmetric [3+2] annulations of 1,4-di-thiane-2,5-diol and oxindole ketimines
Autor: Xin Li, Jiuyuan Li, Jin-Dong Yang, Bo-Xu Feng
Publikováno v: Tetrahedron Letters. 57:3457-3461
An efficient asymmetric [3+2] annulation reaction with respect to isatin N-Boc ketimines and 1,4-di-thiane-2,5-diol has been achieved by using a chiral tertiary-amine squaramide catalyst, which delivering the spirocyclic 3-aminooxindoles in very good

Separation and characterization of squalene and carotenoids derived sulfides in a low mature crude oil
Autor: Quan Shi, Limin Ren, Yahe Zhang, Sumei Li, Chao Ma, Weilai Zhang, Jianxun Wu
Publikováno v: Fuel. 270:117536
An unusual distribution on molecular composition of organic sulfur compounds (OSCs) was found in a crude oil from the Bohai Bay Basin (China) that contains negligible thiophenic sulfur compounds but abundant in C30 and C40 sulfides. The sulfides were
