AbstractThe crystal structure of R(–)‐1‐tosyl‐2‐methylpyrrolidine has been determined by X‐ray structure analysis. The compound crystallizes in the monoclinic space group P21with cell parametersa= 7.858(1),b= 14.929(6),c= 11.128(1) Å, β = 105.42(1)°. The structure has been solved by direct methods and refined toR= 0.046. There are two crystallographically independent molecules A and B in the asymmetric unit. The pyrrolidine ring of molecule A is disordered with atom C4 occupying two possible sites. The S atom has a distorted tetrahedral coordination in both the molecules. Two bifurcated hydrogen bonds are observed. Molecules are held together by
