    Description / Table of Contents: Investigations of Carbenes, XIV. Stereochemistry of rhe Insertion Reaction of Carbenes with C - H-BondsDichlorocarbene reacts with optically active 2-phenylbutane (1) to form inactive 2-dichloromethyl-2-phenylbutane (2). The isotope effect of the reaction is kH/kD = 1.8. Methylene reacts with the HCOCOCH3 group in trans-cyclopentane-1,2-diol-diacetat (3) with inversion.

    Notes: The construction of cell hairs (trichomes) on the wings of Drosophila occurs in synchrony on 30,000 cells over a period of about 20 hr. Changes in both morphology and patterns of protein synthesis occur rapidly during this time period. In this report we describe the use of stressinduced (heat shock) abnormalities in morphogenesis to provide further details on the stepwise processes of differentiation within single wing cells. A cartoon summary of the overall process and a discussion of some possible mechanisms is included.
