摘要：
There are disclosed a compound of the general formula (I): ##STR1## wherein the group R--CO-- is an acyl group and its production. There is also disclosed a process for producing optically active (.+-.)-(3a.alpha., 4.alpha., 6a.alpha.)-tetrahydro-4-acetoxy-1,3-dibenzyl-1H-thieno[3,4-d]imidazol-2(3H)-one by using the compound (I). The compound (I) can be used as an intermediate for producing D-biotin which is useful as medicaments and feed additives for animals.
