Abstract

A . description is ,given of the preparation and properties of
optically active bis(2-carboxy - 2- phthalimidoethyl) disulphide (Ia),
[a]D-275°, bis(2-carboxy -2.:phthalimidoethyl) trisulphide (lb) , ,[a]D
-4720 and bis(2-c arboxy -2-phthalimidoethyl) tetrasulphide (le),
[a]D:--3880. The starting material for these compounds was N -
-phthaloyl-L-cysteine (II), [a]D-64° prepared from L-cysteine
hydrocl).loride and sodium o- carbethoxythiobenzoa te.
