The selective addition of arylmethylmagnesium halides with formaldehyde giving arylethyl alcohols is extremely challenging. To circumvent the difficulties, in the current communication, we have reported on the nucleophilic addition of benzyl zinc reagents derived from inexpensive and abundant benzyl chlorides to paraformaldehyde. The reaction investigated herein is hitherto unknown and was found to be selective, operationally simple, atom- and step-economical and high yielding to deliver phenethyl alcohols utilized as key perfumery ingredients in 60–83% yields. After successful establishment of the reaction condition, the reaction was also scaled up successfully to deliver a large-scale preparation of the phenethyl alcohol.
Pyrrolo[2,3-d] pyrimidines as antiviral agents

Scheme 2, (2010/11/29)
This invention relates to a novel class of 4,5,6,7-substituted non-nucleoside, non-phosphorylatable pyrrolo[2,3-d]pyrimidines which exhibit both significantly lower levels of cytotoxicity and superior antiviral activity than known nucleoside, non-nucleoside, and non-nucleoside, non-phosphorylatable pyrrolo[2,3-d]pyrimidine derivatives, particularly against human DNA viruses such as cytomegalovirus (HCMV) and herpes simplex virus type 1 (HSV-1). These compounds are represented by the following formula: wherein: R4is —NR1R2or oxo; R5is —CN, or —CSNR1R2, or —CONR1R2; R6is —H, or halo, or —NR1R2; wherein R1and R2are independently —H or an aliphatic group; and R7is of the formula R3—Ar, wherein R3is an aliphatic group and Ar is an unsubstituted aryl or an aryl independently substituted with halo, nitro, amino, or aliphatic groups; provided that when R5is a —CN or —CSNH2, and R6is a —H or —NH2, and Ar is a —C6H5or a phenyl substituted with only one aliphatic group, R3is an aliphatic group other than methyl such that —R3— is not a —CH2—; and pharmaceutically acceptable salts, prodrugs and derivatives thereof.
