  1-Alkenesulfinyl Chlorides:  Synthesis, Characterization, and Some Substitution Reactions

  摘要：

  A number of 1-alkenyl sulfoxides bearing either a diphenylmethyl (DPM) or a p-methoxybenzyl (PMB) group have been prepared and exposed to the chlorine surrogate SO2Cl2. Through an oxidative fragmentation reaction, a new family of sulfur acid derivatives, 1-alkenesulfinyl chlorides, is generated. They can be characterized by IR spectroscopy before chemical capture with an alcohol. Ethenesulfinyl chloride (2a) and 1-propenesulfinyl chloride (2b), obtained from their corresponding DPM precursor, can be distilled at reduced pressure to afford ca. 90% pure material. NMR chemical shift comparison of various 1-alkenesulfinyl-containing compounds is made. 1-Alkenesulfinylmethyl phenyl(alkyl) ketones (6) can be prepared directly from sulfinyl chlorides 2 although decomposition and/or isomerization is sometimes extensive during purification.

  A number of alpha,beta -unsaturated sulfinyl chlorides 1 has been separately prepared and treated with (-)-cholesterol under various conditions some of which incorporated chiral amines quinine or quinidine. Some (R-S) vinylic sulfinates could be isolated in enantiopure form following one or two recrystallizations of the resulting diastereomeric mixtures of (-)-cholesteryl 1-alkenesulfinates 2. Access to diastereomerically enriched (S-S) vinylic sulfinates (66-75% de) was achieved in three instances. Absolute stereochemical assignments were made with the assistance of the chiral solvating agent (R)-2,2,2-trifluoro-1-(9-anthryl)ethanol. (C) 2001 Elsevier Science Ltd, All rights reserved.
