Organic molecules in the protoplanetary disk of DG Tau revealed by ALMA [PDF]
, 2019 Planets form in protoplanetary disks and inherit their chemical compositions. It is thus crucial to map the distribution and investigate the formation of simple organics, such as formaldehyde and methanol, in protoplanetary disks.

An unexpected ring formation in morphine chemistry
Arkivoc, 2001 Reaction of (7R)-N-benzyl-N-nor-7-bromoneopinone dimethyl acetal (2) with primary or secondary amines (RNH2, R1R2NH) resulted in 9-amino-substituted hasubanan derivatives; in particular, modification of the 9-(2-hydroxyethyl)amino derivative in subsequent steps gave products 8 with a 9-(oxazolidin-2'-one-3'-yl) substituent.
