Borrowing Hydrogen (BH), also called Hydrogen Autotransfer (HA), reaction with neat ethylene glycol represents a key step in the preparation of β-amino alcohols. However, due to the stability of ethylene glycol, mono-activation has rarely been achieved. Herein, a combination of Pd/C and ZnO is reported as heterogeneous catalyst for this BH/HA reaction. This system results in an extremely air and moisture

A “Pictet-Spengler-like” reaction between azalactones 1 and conformationally constrained tryptamines 4 in refluxing 1N HCl over 72 h. gave the corresponding tetrahydro-β-carbolines 3 in moderate to good yields. The observed equatorial orientation of the C-1 substituent in the THBC's results from a combination of the thermal reaction conditions and conformational constraints imposed by the starting
