3-Mercaptodihydrocarvone (True Carvone Hydrosulphide) and (IS, 4S, 5S)-4,7,7-Trimethyl-6-thia-l,5-bicyclo-[3,2,l]-octan-3-one

چکیده

Whereas the compound formerly known as carvone hydrosulphide is, in fact, dicarvone sulphide [1], the genuine hydrosulphide, (—)-3-mercaptodihydrocarvone, has now been prepared by the addition of hydrogen sulphide to (—)-carvone in the presence of a base following a procedure analogous to that of van Tamelen and Grant [2]. Tt had boiling point 150-151 °/0.5 mm, ri&, 1.5221 [a]2i? —6.3° (c = 4 in chloroform, 1=1 ) . Altogether, three products were obtained and part of the ketone was recovered. One of the products was identified by melting point and infrared spectrum as that previously styled carvone hydrosulphide, here called dicarvone sulphide 1.
