4-Boc-Piperazinone

The Synthesis of Bicyclic Piperazinone and Related Derivatives

We have been examining synthetic approaches to conformationally restricted peptide building blocks that would allow for the construction of a variety of possible structures in a straight-forward, general way ( 1 ). To date, this effort

Synthesis of Peptides Using Tert-Butyloxycarbonyl (Boc) as the -Amino Protection Group

The use of the tert -butyloxycarbonyl (Boc) as the N α-amino protecting group in peptide synthesis can be advantageous in several cases, such as synthesis of hydrophobic peptides and peptides containing ester and thioester moieties

关于boc-氨基酸做成酰氯的疑问

问：看了园子里很多帖，有关氨基酸是否可以做成羧基上的酰氯，有人说fmoc保护的还可以，但是手头就只有boc保护的，于是想了下合成方案，望高手指点，就是在低温下（可能冰水中）boc-氨基酸：socl2=1：1（2：1）条件下，用甲苯作溶剂，三乙胺做傅酸剂缓慢滴加来促使boc-氨基酸做成酰氯，希望大家提提意见，是否可行？谢谢。答：请注意，EDC/DCC等不是催化剂，要加化学计量的，不知道“反应效率有限”是指什么意思。做成酰氯可能不容易实现。如果想进一步探讨，请给出反应的结构式、已经尝试过的条件
