Hydroxyalkyl phenols can be protected either at the hydroxy group or at the
phenol in a simple protocol (CH2Cl2, Et3N, DMAP, 0 degrees C --> room temp
.) by using either t-butyldimethylsilyl chloride or trityl chloride as prot
ecting reagent. Yields are in the range of 37-92%. (C) 1999 Elsevier Scienc
