The two most commonly used types of allyl alcohol linker are 4-hydroxycrotonic acid derivatives (Entry 1, Table 3.7) and (Z)- or ( )-2-butene-l, 4-diol derivatives (Entries 2 and 3, Table 3.7). The former are well suited for solid-phase peptide synthesis using Boc methodology, but give poor results when using the Fmoc technique, probably because of Michael addition of piperidine to the a, 3-unsaturated carbonyl compound [167]. Butene-l,4-diol derivatives, however, are tolerant to acids, bases, and weak nucleophiles, and are therefore suitable linkers for a broad range of solid-phase chemistry. [Pg.55]

Since our initial report (9) on this subject, Yokoyama and Hall (10) published their results on the free-radical initiated copolymerization of IA with MA to obtain a 1 1 alternating copolymer. Yokoyama and Hall (10) also confirmed that the IA-MA copolymer is a source of head-to-head poly (4-hydroxycrotonic acid). [Pg.372]

Furthermore, GHB can be further metabolized by p-oxidation to trans-4-hydroxycrotonic acid, which aisc can bind to the GHB receptor. Body builders use these compounds as well in an attempt to enhance the release of growth hormone. Usually, however, chronic abuse leads to tolerance, with a need to increase dcsing and a prcpensity to produce physical dependence (43). A sericus and difficult-to-treat withdrawal syndrcme frcm GHB abuse has been dccumented. [Pg.649]
