Abstract Acyclic and cyclic acetates of various alcohols and phenols were obtained in excellent yields under mild reaction conditions in the presence of a catalytic amount of sodium hydroxide under solvent–free conditions and microwave irradiation. Selective deprotection of acetate group from the corresponding phenolic compounds was carried out in the presence of LiClO4.2H2O.

A highly efficient in situ N-acetylation approach for solid phase synthesis.
A new general N-acetylation method for solid phase synthesis that can be easily applied to acetylation in a wide variety of chemical reactions performed on the solid phase is described.
Inactivation of an aminoaldehyde dehydrogenase is responsible for fragrance in rice
Findings on the pathway of fragrance generation in Basmati and Jasmine rice and the potential of rice to accumulate the osmoprotectant glycine betaine are discussed.
In the process of crude palm oil (CPO) to be lubricant, homogeneous acid catalyst is commonly used. This kind of catalyst has some disadvantages including the difficulty to remove well from the
Identification of the gene responsible for fragrance in rice and characterisation of the enzyme transcribed from this gene and its homologs
Development of an allele specific amplification (ASA) based around the deletion in the gene encoding BAD2 allows, perfect, simple and low cost discrimination between fragrant and non-fragrant rice varieties and identifies homozygous fragrant, homozygously non-Fragrant and heterozygous non- fragrant individuals in a population segregating for fragrance.


A New Protocol for O-Methylation of Phenolic Compounds with Trimethyl Phosphite or Trimethyl Phosphate Under Solvent-Free Condition and Microwave Irradiation
A simple method for the preparation of industrially important alkyl aryl ethers is reported. Several phenolic compounds such as phenols, naphthols, and hydroxy coumarins were O-methylated with
