Stereospecific synthesis of dl-cyclopenin and dl-cyclopenol
Tetrahedron, 1970Abstract A stereospecific synthesis of dl -cyclopenin ( 1 ) is described corroborating previous structural and stereochemical assignments. The hippuric acid 10 was converted to cis ester 11 which was reduced and cyclized separately to cis and trans 3-benzylidene-4-methyl-1- H -1,4-benzodiazepin-2,5-diones 12 and 14 .
