Structure of 10,10-dihydro-10-deoxo-10a-methyl- 10a-aza-10a-homoerythronolide A

C22H43NO7, Mr = 433.58, monoclinic, P21. The geometry and dimensions of the 15-memebered aglycone ring are not significantly different from those found in the analogous azaerythronolide A derivatives. The presence of the methyl group linked to the N atom does not significantly influence the structure. The distances between O...O atoms (282 to 286 pm) suggest the existence of inter- and intramolecular hydrogen bonds.
