Dear ABRFers,

I am preparing peptides using a benzoylated derivative of mercaptoacetic
acid, a cyseine analog. I have heard rumous that s-benzoyl protected
cysteine was used as a protecting group for boc chemistry in the distant
past. Are there any old-timers out there who confirm or deny this? I
would appreciate any references if you have some handy.

Sincerely,

Gary Van Domselaar
