Syntheses of 1-Hydroxytryptamines and Serotonins Having Fattyacyl or (E)-3-Phenylpropenoyl Derivatives as an Nb-Substituent, and a Novel Homologation on the 3-Substituent of the 1-Hydroxytryptamines upon Treatment with Diazomethane
摘要:
1-Hydroxytryptamines (6a-f) having (E)-3-phenyl-, (E)-3-(4-hydroxypheny)-, (E)-3-(4-hydroxy-3-methoxyphenyl)propenoyl, octanoyl, hexadecanoyl, and docosanoyl group as a Nb-substituent are prepared for the first time. Preparations of serotonins (2a- c, e) from the corresponding 1-hydroxytryptamines (6a- c, e) are also reported. A novel homologation on the 3-substituent of 1-hydroxytryptamines is discovered upon treatment with diazomethane in chloroform or dichloromethane.
