Application of 52079-23-9, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.52079-23-9, Name is (S)-(-)-alpha-Hydroxy-gamma-butyrolactone, molecular formula is C4H6O3. In a article，once mentioned of 52079-23-9
The homochiral 1,3-dioxanes 8a-e with a 2-bromophenyl substituent in position 2 and an electrophilic group in position 4 were stereo- and regioselectively prepared from the (S)-malic acid derivatives 6a, 6b, 11, and 14. Attempts to prepare the tricycles 5a-c by connecting the 2-phenyl substituent with the electrophilic groups in position 4 of 8a-e in a Parham cyclization across the 1,3-dioxane ring failed. The synthesis of the tricyclic title ketone 5a succeeded, however, by addition of the lithiated benzaldehyde acetal 7c to the protected alpha-hydroxylactone 10b and subsequent treatment of the intermediate ketone 23 with acid. The acid hydrolysis of the alcohol 26, which was obtained by addition of 7c to the protected dihydroxy aldehyde 25b, followed by oxidation of the resulting alcohols 27 a and b represent a second possibility for the preparation of the tricyclic ketone 5a.
