1. General information
All reagents were obtained from commercial sources and used as received. Erythritol (>99%
purity) was purchased from Sigma-Aldrich. Pentaerythritol (>98% purity) was purchased from
ACROS. Valeraldehyde, octanal, decanal and dodecanal were supplied by Sigma-Aldrich or
Alfa-Aesar. Camphorsulfonic acid was purchased from Chimex, Amberlyst 35 were bought
from Rohm and Haas. Pd/C (5 or 10%, Pd on activated carbon, reduced and dry, Escat 1431)
was purchased from Strem Chemicals. All other reagents and solvents were used as received
without further purification. Reactions were monitored by TLC or GC and chromatographic
separations were performed over silica gel 60H (40-63μ). Acetalisation were carried in a 20mL
sealed tube and methylation in 50mL sealed tube. Direct reductive alkylations were undertaken
in a 300mL steel Parr autoclave equipped with a mechanic stirrer.
All compounds were characterized by spectroscopic data. The nuclear magnetic resonance
(NMR) spectra were recorded either on a Bruker ALS 300 (1H: 300 MHz, 13C: 75 MHz), a
DRX 300 (1H: 300 MHz, 13C: 75 MHz) or a Bruker DRX 400 (1H: 400 MHz, 13C: 100 MHz)
spectrometer, in CDCl3 or DMSO-d6 at 293K. Chemical shifts are reported in parts per million
(ppm) and are calibrated on residual solvent peaks: CDCl3 7.16 ppm in 1H and 77.16 ppm in 13C, or DMSO-d6 2.50 ppm in 1H and 39.52 ppm in 13C. Spin-spin coupling constants (J) are

given in Hz. The peak patterns are indicated as follows: (s, singlet; d, doublet; t, triplet; q,
quartet; m, multiplet, and br. for broad).
IR spectra were recorded by using a Spectro Nicolet IS10 Smart ITR instrument with an
Attenuated Total Reflectance (ATR) diamond.
ESI HRMS mass spectra were recorded in positive-ion mode by using a hybrid quadrupole
time-of-flight mass spectrometer (Micro-TOFQ-II, Bruker Daltonics, Bremen) with an ESI ion
source. The flow of spray gas was 0.4 bar, and the capillary voltage was 3.5 kV. The solutions
were infused at 10 mL.min-1 in a mixture of solvents (methanol/
dichloromethane/water=45:40:15). The mass range of the analysis was m/z=50–1000, and the
calibration was performed with sodium formate.
GC analyses were performed on a Shimadzu Gas Chromatograph GC-2025 equipped with a
ZB-5-MS column (30.0 m × 0.25mm × 0.25µm). The carrier gas was N2 at a flow rate of 1.27
mL/min. Column temperature was initially 70 °C for 2 min, then gradually increased to 310 °C
at 15 °C/min and finally kept at 310 °C for 10 min. The injector temperature was 280 °C and
for detection a FID was used at 315 °C.
General procedure for the preparation of acetals.
In a round bottom flask equipped with a condenser fitted with a CaCl2 guard, under an argon
atmosphere, the corresponding polyol (10.00 g, 85.0mmol, 3 equiv.) was dissolved in dry EtOH.
The aldehyde (27.3 mmol, 1 equiv.) was added dropwise, followed by camphorsulfonic acid
(10 wt%/aldehyde). Then, the mixture was magnetically stirred at 80 °C for 15 hours. The
mixture was cooled down to room temperature and the solvent was evaporated under reduced
pressure. The residue was triturated in EtOAc and the excess of polyol was filtered off and
washed with cold EtOAc. This operation was repeated two times in order to remove any traces
of polyol. The residue was concentrated, in the case of erythritol, a mixture of regioisomers
acetals were obtained. The ratio of compounds has been determined by H1 NMR. Acetal is
crystalized with the minimum of diethylether in a 250mL round bottom flask. The solution is
cold-filtered by a sintered glass. Purified acetal contained in the solid part is dried under reduced
pressure.
General procedure for the recycling of acid catalyst and excess of polyol.
Same protocol as described above was made for the acetalisation, but after cooling, the acid
resin and the excess of polyol recrystallized and filtrated were dried under vacuum. The mixture
of polyol and acid resin obtained was completed by fresh polyol to restart acetalisation.
General procedure for the preparation of corresponding ethers.
The corresponding acetal (10 mmol) was diluted in dry CPME (100 mL) and 5%-Pd/C (1.06 g,
5 mol% in Pd) was added in a 300 mL stainless steel autoclave. The reactor was tightly closed,
purged three times with hydrogen and hydrogen pressure was introduced (30 bar). The system
was heated at 130 °C and mechanically stirred for 15 hours. After cooling to room temperature,
hydrogen pressure was released and the reaction mixture was then dissolved in EtOAc (100
mL), filtered (Millipore Durapore filter 0.01 μm), and washed two times with 20 mL of EtOAc.
The filtrate was evaporated under reduced pressure and the residue was purified by flash
chromatography to give corresponding ethers, in erythritol case, a mixture of 2 regioisomers
were obtained. The ratio of compounds has been determined by GC.
Thermogravimetric analysisThermoGravimetric Analysis (TGA) experiments were performed with a TA Instruments TGA
Q500 apparatus. Approximately 20 mg of each compound was introduced into a platinum
crucible and a temperature ramp of 5 °C/min was applied from 20 °C to 300 °C under nitrogen
atmosphere. The decrease of the mass was followed as a function of time and temperature.

The table 1 described the values of the second endothermic peak observed by DSC, which are
assigned to the boiling point or the decomposition temperature of the compounds.
ThermoGravimetric Analysis (TGA) is carried out to distinguish whether the endothermic
peaks observed with O-alkylerythritol and O-alkylpentaerythritol correspond to the boiling or
degradation of the compound tested. Since the ATG analysis is carried out in an open capsule
and under a stream of nitrogen, compounds evaporate at a temperature substantially below its
boiling point (T ≈ 60-100°C), thus avoiding its decomposition. Figure 1 shows the TGA
profile of the O-alkylpentaerythritol derivatives
