| titleOfInvention | Tricyclic compounds containing heteroatoms |
| abstract | 1. Tricycic compounds containing heteroatoms, characterized in that they are compounds of formula a, in which Q is a group of formula b or a group of formula c, or a group of formula d, bond 1 being assigned to the nitrogen-containing ring , bond 2 is assigned to a carbonyl group and bond 3 is assigned to a carbon having a methoxy group wherein R1 is a hydroxyl group optionally protected by a tert-butyldimethylsilyl group or by a methylsulfonyl group and R1a is hydrogen or R1 and R1a together are oxo, R2 is a hydroxyl group optionally protected by a tert-butyldimethylsilyl group or together with R4 forms an -OC (= O) O- group; R3 is ethyl or a 11 and 1; R4 is hydroxy optionally protected by a tert-butyldimethylsilyl group or together with R2 forms a -OC (= O) O- group, and R4a is hydrogen or R4 together with R4a is oxo; R5 is methoxycarbonylxyl, chlorine, a hydroxyl group optionally protected by a tert-butyldimethylsilyl group, by a tert-butoxycarbonyl group or by a methylsulfonyl group; methoxy group; formyloxy, acetyloxy or benzoyloxy or the group -OC (= O) N (R10) R11, wherein R10 and R11 are independently hydrogen or methyl, or together with the nitrogen atom to which they are attached form a 4-morpholinyl group; or R5 together with R6a forms the group -OC (= X) N (R'10) - where, X is O or S and R'10 is hydrogen or methyl, or R5 together with R8a is oxy, with R8 is hydroxy, R6 is hydroxy and R6a is hydrogen, or together with R5 forms an -OC (= X) N (R'10) group as defined above; or R6 and R6a taken together are oxo; R'5 is a hydroxyl group, optionally protected benzoyl or acetyl, and R'6 is a hydroxyl group.
