摘要:The present invention relates to a method for preparing 4-hydroxy-2-methylene-butanal, 4-hydroxy-2-methyl-but-2-enal and esters thereof of the formula (I.a) and (I.b) where R1 is as defined in the claims and the description, by subjecting isoprenol or an ester thereof to a photooxidation in the presence of a photosensitizer and an acylating agent. The invention relates moreover to certain hydroperoxides of the compounds (I.a) or (I.b), and to the use thereof as intermediates in the synthesis of compounds (I.a) and (I.b) or in the synthesis of retinol, stereoisomers and derivatives thereof.

摘要:A polymer-free synthesis method is provided for preparation of monodisperse nanostars. The nanostars can be used for treating and imaging cells in in vivo or ex vivo. The modes of treatment include use of a nanostar modified with a photo-activatable drug, which drug is activated by the photo-response of the nanostar to electromagnetic stimulation; use of a nanostar modified with a thermally-activatable drug, which drug is activated by a thermal response of the nanostar to electromagnetic stimulation; and the thermal response of the nanostar itself to electromagnetic stimulation, which can directly or indirectly cause the death of an undesirable cell.
