Abstract
A phytochemical investigation of the rhizomes of Curcuma zedoaria was carried out, leading to the isolation of a new diphenylheptanoid, zedoaroxane A (1), together with four known compounds (2-5). Their structures were elucidated based on NMR spectroscopic data. All isolated compounds possessed α-glucosidase inhibitory activity, with the IC50 values ranging from 35.2 to 89.0 µM, more potent than that of the positive control acarbose (IC50, 214.5 µM).

Abstract
A stereoselective total synthesis of (−)-cryptocaryol A (1) is described. Key features of the 17-step route include the use of three boron-mediated aldol reaction–reduction sequences to control all stereocenters and an Ando modification of the Horner–Wadsworth–Emmons olefination that permitted the installation of the Z double bond of the α-pyrone ring.

Abstract
Ultrafast (UF) 2D NMR makes it possible to obtain a 2D NMR spectrum in less than a second. Here, UF-HSQC experiments are used for the real-time mechanistic study of an acetal hydrolysis at ¹³C natural abundance, and it is possible to characterize the presence of the hemiacetal, an intermediate with a well-known short lifetime. The assignments are confirmed and rationalized by quantum calculations of ¹H and ¹³C NMR chemical shifts and natural bonding orbital analysis.
