Two new carbasugars (9 and 10) were isolated from Streptomyces lincolnensis DSM 40355 along with streptol (valienol, 8), gabosine I (valienone, 14), and glucosylglycerate. The reported (1)H and (13)C assignments are based on 1D ((1)H, (13)C, 1D-TOCSY, homodecoupling) and 2D (gCOSY, J-resolved, TOCSY, ROESY, gHSQC, gHMBC) NMR techniques and electrospray ionization FT mass spectrometry (ESI FTMS).
